Thanks for sharing the ComfyUI log. Based on this output, your setup is mostly working but there are **two key issues** to address: --- ### ⚠️ Issues #### 1. **`Failed to restore comfyui-frontend-package`** This likely means the UI assets (frontend files like JS/CSS for the GUI) didn’t restore correctly. **Fix:** Try reinstalling the frontend manually: ```bash cd /Applications/ComfyUI.app/Contents/Resources/ComfyUI git clone https://github.com/comfyanonymous/ComfyUI.git frontend ``` Or if it's already there but corrupted, delete and re-clone the `frontend` or reinstall via the ComfyUI-Manager GUI if available. --- #### 2. **`sqlite3.OperationalError: unable to open database file`** This error is coming from the ComfyUI-Manager trying to access or create a SQLite database but failing due to file permissions or path issues. **Fix:** Make sure the `user/default/ComfyUI-Manager/` folder exists and has proper write permissions. You can run: ```bash mkdir -p ~/Documents/ComfyUI/user/default/ComfyUI-Manager chmod -R 755 ~/Documents/ComfyUI/user/ ``` If the file it’s trying to open is hardcoded and missing, you can also manually touch it: ```bash touch ~/Documents/ComfyUI/user/default/ComfyUI-Manager/comfyui_manager.db ``` --- ### ✅ Everything Else Seems Fine - Your install is running on **macOS 15.5** (Sonoma). - Using **PyTorch 2.7.1** and **Python 3.12.9**. - It correctly detects your system has **48 GB of RAM/VRAM**, and defaults to `cpu` execution. - Model loading, VAE, and registry fetches all complete successfully. --- ### 💡 Optional Optimizations - Since you're running CPU-only, consider enabling: ```bash --use-split-cross-attention ``` if you're seeing performance issues. - Add the following alias or shell script to simplify launching in a terminal if needed: ```bash alias comfyui='cd /Applications/ComfyUI.app/Contents/Resources/ComfyUI && source .venv/bin/activate && python main.py' ``` --- Would you like a minimal CLI script to fully reinstall the ComfyUI frontend and fix permissions in one go?

Thanks, this updated log confirms the **same two issues are persisting**, but everything else is functioning smoothly: --- ## ✅ What’s Working - **ComfyUI is running and responsive.** - Models are loading on `CPU`. - Custom nodes (`videohelpersuite`, `websocket_image_save.py`) are successfully imported. - Prompt processing and ComfyRegistry fetching is proceeding without issues. --- ## ❗ What’s Still Broken ### 1. `Failed to restore comfyui-frontend-package` This happens because ComfyUI is **not inside a Git repository**, and so ComfyUI-Manager can’t fetch/update the frontend. #### ✅ Fix: If you’re using the **App version** from `.dmg` or `.app`, it doesn’t come as a Git repo. To fix this: **Option A: Switch to Git-Based Install (recommended for devs)** ```bash # Backup anything custom first cd ~/Documents git clone https://github.com/comfyanonymous/ComfyUI.git cd ComfyUI python -m venv .venv && source .venv/bin/activate pip install -r requirements.txt python main.py ``` **Option B: Ignore this Warning** This issue only matters if you want **live updating from ComfyUI-Manager**. If the frontend works, you can ignore this warning unless a feature you need is missing or broken. --- ### 2. `sqlite3.OperationalError: unable to open database file` ComfyUI-Manager can’t write to its SQLite DB file. #### ✅ Fix: Run the following to **ensure proper path and permissions**: ```bash mkdir -p ~/Documents/ComfyUI/user/default/ComfyUI-Manager touch ~/Documents/ComfyUI/user/default/ComfyUI-Manager/comfyui_manager.db chmod -R 755 ~/Documents/ComfyUI/user ``` > If that still fails, try deleting the entire `~/Documents/ComfyUI/user/default/ComfyUI-Manager/` folder and letting ComfyUI recreate it. --- ## 🛠 Optional: Minimal One-Liner Fix Script (macOS Bash) ```bash mkdir -p ~/Documents/ComfyUI/user/default/ComfyUI-Manager && \ touch ~/Documents/ComfyUI/user/default/ComfyUI-Manager/comfyui_manager.db && \ chmod -R 755 ~/Documents/ComfyUI/user ``` --- Would you like me to write a full shell script that auto-fixes both issues and relaunches ComfyUI for you?

You're **almost there** — ComfyUI is fully functional, but the **two warnings persist**. Here's a final summary **with a full fix script** to clean it up completely. --- ## 🛑 Errors Still Occurring ### 1. `Failed to restore comfyui-frontend-package` **Reason:** Your `.app` install isn't a Git repo, so it can't update the frontend automatically. 🔧 **Solution:** Either ignore it if the GUI works, **or use a Git-based install instead**. --- ### 2. `sqlite3.OperationalError: unable to open database file` **Reason:** The ComfyUI-Manager can't create or access its SQLite DB, usually due to: - Missing `comfyui_manager.db` file - Incorrect folder permissions 🔧 **Solution: Fix directory and permissions.** --- ## ✅ One-Line Terminal Fix (Paste this in Terminal) ```bash mkdir -p ~/Documents/ComfyUI/user/default/ComfyUI-Manager && touch ~/Documents/ComfyUI/user/default/ComfyUI-Manager/comfyui_manager.db && chmod -R 755 ~/Documents/ComfyUI/user ``` This: - Creates the required folder structure - Ensures a blank SQLite DB exists - Grants proper permissions for reading/writing --- ## 🧰 Optional: Full Shell Script to Repair Everything If you'd like to run a more robust script that: - Fixes the DB issue - Preps you for switching to Git-based ComfyUI - Makes launching easier ```bash #!/bin/bash echo "🔧 Fixing ComfyUI-Manager DB permissions..." mkdir -p ~/Documents/ComfyUI/user/default/ComfyUI-Manager touch ~/Documents/ComfyUI/user/default/ComfyUI-Manager/comfyui_manager.db chmod -R 755 ~/Documents/ComfyUI/user echo "✅ Database folder prepared." echo "🧹 (Optional) Cleaning frontend package errors — this won't affect function if you're using the .app version." # Optional Git clone setup instructions read -p "Do you want to clone ComfyUI as a Git repo (recommended for devs)? [y/N] " yn if [[ $yn == [Yy]* ]]; then cd ~/Documents git clone https://github.com/comfyanonymous/ComfyUI.git cd ComfyUI python3 -m venv .venv && source .venv/bin/activate pip install -r requirements.txt echo "🚀 Run with: source .venv/bin/activate && python main.py" else echo "👍 Staying on the .app version. Errors will be cosmetic only." fi ``` Save this as `fix_comfy.sh`, then run: ```bash chmod +x fix_comfy.sh ./fix_comfy.sh ``` --- Let me know if you want to **migrate your models/custom nodes** into the Git version cleanly — I can script that too.

missing VHS_VideoCombine

The error `missing VHS_VideoCombine` means that **ComfyUI can't find the `VHS_VideoCombine` node**, which is part of the **`comfyui-videohelpersuite`** custom node pack you're using. --- ## ✅ Steps to Fix `VHS_VideoCombine` Missing ### 1. **Check That You Installed the Correct Repo** The node should come from: 👉 **Repo:** [https://github.com/WASasquatch/comfyui-videohelpersuite](https://github.com/WASasquatch/comfyui-videohelpersuite) If it's not that exact one, delete your current one and reinstall it: ```bash cd ~/Documents/ComfyUI/custom_nodes rm -rf comfyui-videohelpersuite git clone https://github.com/WASasquatch/comfyui-videohelpersuite.git ``` --- ### 2. **Make Sure It’s Properly Installed** After cloning, make sure the path looks like this: ```bash ~/Documents/ComfyUI/custom_nodes/comfyui-videohelpersuite/__init__.py ~/Documents/ComfyUI/custom_nodes/comfyui-videohelpersuite/nodes/VHS_VideoCombine.py ``` If `VHS_VideoCombine.py` is missing, the node isn't in the repo or it changed names. --- ### 3. **Verify the Node Is Registered** Restart ComfyUI completely and watch for output like: ``` Loaded custom node: VHS_VideoCombine ``` If you don’t see that, it's not being picked up. --- ### 4. **Force Reload ComfyUI Nodes** You can also do this in the ComfyUI web interface: - Open http://127.0.0.1:8000 - Use the "Manager" tab - Click **Reload Custom Nodes** Or do it via CLI: ```bash pkill -f ComfyUI # or just close the app python main.py # or re-launch ComfyUI ``` --- ### 5. **Check for Errors in Logs** If it's still missing, check `~/Documents/ComfyUI/user/comfyui.log` for messages related to `VHS_VideoCombine`. Common problems: - Python syntax error in the node file - Missing dependencies (e.g., `ffmpeg-python`, `moviepy`) Install video dependencies if needed: ```bash pip install ffmpeg-python moviepy ``` --- Would you like me to fetch or recreate a working version of `VHS_VideoCombine` for your current version of ComfyUI?

got prompt invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#48'", 'extra_info': {}}

That error means **one of the nodes in your workflow is broken or partially loaded**, specifically: > **`Cannot execute because a node is missing the class_type property.`** > → Node ID: `#48` --- ## 🧠 What This Error Means Every node in a ComfyUI graph must define a `class_type` (usually the name of the node class, like `VHS_VideoCombine`, `KSampler`, etc.). When that property is missing: - The node is *not recognized* as a valid node type - ComfyUI **refuses to run the graph** - You get the “invalid prompt” error --- ## ✅ How to Fix It ### 1. **Find and Delete/Replace the Broken Node** Open the ComfyUI GUI: - Go to [http://127.0.0.1:8000](http://127.0.0.1:8000) - Look for a **gray box** or a node with a **red header**, probably marked `#48` - Hover over it, and you'll likely see no title or "missing node" - **Delete it** or **replace it** with the correct one --- ### 2. **Reimport or Reinstall the Node That Was Supposed to Be There** If this came from a saved workflow (`.json`), then it relied on a node that: - **No longer exists** (e.g., you deleted `comfyui-videohelpersuite`) - **Was renamed** (node class changed name) - **Failed to register** during startup 🔧 Fix: - Reinstall the node repo (like `comfyui-videohelpersuite`) - Check it registers cleanly - Restart ComfyUI --- ### 3. **Optional: Edit the Prompt JSON Manually** If you want to salvage your `.json` workflow without the broken node: 1. Open your workflow file in a text editor. 2. Find the object with `"id": 48`. 3. Delete that node block. 4. Also delete any connection edges that reference node 48. 5. Save and reimport into ComfyUI. --- ## 🚨 Bonus Tip: Enable Developer Logs To see these errors more clearly in the ComfyUI UI: - Go to the browser dev console (`Cmd+Option+I` on Mac) - Reload the page - See if any broken nodes throw tracebacks during UI load --- Would you like me to analyze or auto-repair a workflow `.json` file if you upload it here?

``` ## Additional Context (Please add any additional context or steps to reproduce the error here)

Thanks for the thorough report. Here's exactly what went wrong and how to fix it: --- ## ❌ Problem Summary **Node `#48` (`VHS_VideoCombine`) is invalid** because the `ComfyUI-VideoHelperSuite` failed to load. This happened due to: ``` ModuleNotFoundError: No module named 'cv2' ``` So the node class `VHS_VideoCombine` was never registered → its `class_type` is missing → ComfyUI cannot execute the graph. --- ## ✅ Fix (Step-by-Step) ### 1. ✅ **Install `opencv-python`** The missing `cv2` module is part of OpenCV, which `VideoHelperSuite` depends on. From your ComfyUI virtual environment, run: ```bash /Users/danielkliewer/com01/ComfyUI/.venv/bin/python -m pip install opencv-python ``` Or, if you’re not in the venv: ```bash cd /Users/danielkliewer/com01/ComfyUI source .venv/bin/activate pip install opencv-python ``` --- ### 2. 🔁 **Restart ComfyUI** Close and relaunch ComfyUI so it reattempts to load the `ComfyUI-VideoHelperSuite` custom node. Watch for logs confirming successful load, like: ``` Import times for custom nodes: ... ComfyUI-VideoHelperSuite: 0.2 seconds ``` --- ### 3. ✅ **Try the Workflow Again** Now you should be able to queue the workflow successfully — the `VHS_VideoCombine` node will have a valid `class_type`. --- ## 🛠 Optional: Fallback If You Don’t Want to Use That Node If you don't need video combining: - Open the workflow in the UI - Find node `#48` (gray/missing or error-looking) - Delete it - Remove related links (e.g. from node `#8` to `#48`) - Replace it with a different export node (e.g., `SaveImage`, `ImagePreview`) --- ## 🧠 Bonus: Verify All Required Dependencies If you're working with video tools in ComfyUI, it's a good idea to also install: ```bash pip install imageio[ffmpeg] moviepy av ``` --- Let me know if you want me to repair and upload a fixed version of that workflow `.json` that doesn’t require `VideoHelperSuite`.

invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#48'", 'extra_info': {}}

`Node #48` is still “class-less” because **ComfyUI never succeeded in loading the `ComfyUI-VideoHelperSuite` package**. Until that custom package imports cleanly, every workflow that contains `VHS_VideoCombine` (or any other VHS_* node) will stay broken. --- ## 1 Why the package is still failing ``` ModuleNotFoundError: No module named 'cv2' ``` ### 👉 The real snag You are running **Python 3.13.5**. At the moment the pre-built wheel for **opencv-python** (which supplies `cv2`) has not been published for 3.13, so a plain `pip install opencv-python` silently falls back to “build-from-source,” and on macOS that compile usually fails or pulls in the wrong architecture. --- ## 2 Fix paths & deps once and for all | Step | What to do | Exact command | |------|------------|---------------| | **A** | Activate the same venv ComfyUI uses | ```bash\ncd /Users/danielkliewer/com01/ComfyUI\nsource .venv/bin/activate\n``` | | **B** | Install a wheel that *does* exist | ```bash\npip install opencv-python-headless==4.9.0.80\n```<br>(4.9.0.80 has universal wheels up to macOS ARM, and “headless” is fine for CLI/ffmpeg work.) | | **C** | Add the other video helpers (one-liners, all have 3.13 wheels) | ```bash\npip install imageio[ffmpeg] moviepy av\n``` | | **D** | **Hard-restart** ComfyUI | Close the GUI / quit the terminal process and launch again (`python main.py`). Watch the log: you should **NOT** see the `cv2` error anymore and you should see something like:<br>`[VideoHelperSuite] Registered 26 nodes …` | If you prefer to stay on a fully supported Python version, you can downgrade the venv to **Python 3.12** (opencv has wheels there), but the quick headless wheel above is usually enough. --- ## 3 If you just want to run the workflow right now 1. Open the graph in the browser. 2. Delete the grey/red **`VHS_VideoCombine`** box (that’s node 48). 3. Connect node 8’s `IMAGE` output to a simple `SaveImage` or `PreviewImage` node instead. 4. Queue the prompt – it will work immediately because nothing depends on `cv2`. --- ## 4 Verify success - **Good path:** ``` Import times for custom nodes: … ComfyUI-VideoHelperSuite: 0.2 s ``` No more `ModuleNotFoundError`. - **Bad path (still broken):** You still see `IMPORT FAILED` for VideoHelperSuite and node #48 errors keep popping up. --- ### Need a cleaned workflow file? Upload the `.json` and I’ll strip out the VHS nodes (or replace them) and send you back a ready-to-run version.

invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#48'", 'extra_info': {}}

You're seeing this error because **Node #48 (`VHS_VideoCombine`) is broken** — ComfyUI cannot find its `class_type`, which happens when a custom node fails to load during startup. The root cause is already in your logs: ``` ModuleNotFoundError: No module named 'cv2' ``` The `ComfyUI-VideoHelperSuite` requires the `cv2` module (from `opencv-python`), but it's missing from your Python environment — likely because you're using **Python 3.13**, which currently **has no official `opencv-python` wheels**. --- ### ✅ **Fix the issue in 3 steps**: #### **1. Activate your ComfyUI virtual environment** Run this in your terminal: ```bash cd /Users/danielkliewer/com01/ComfyUI source .venv/bin/activate ``` --- #### **2. Install a compatible version of OpenCV** Use the headless version (no GUI libs) which works on macOS and has wheels up to Python 3.13: ```bash pip install opencv-python-headless==4.9.0.80 ``` You can also install other optional video dependencies: ```bash pip install imageio[ffmpeg] moviepy av ``` --- #### **3. Restart ComfyUI** Completely quit ComfyUI and relaunch it (`python main.py`), or restart the app if using the GUI. Watch the logs carefully: - You **should not** see the `ModuleNotFoundError: No module named 'cv2'` anymore. - You **should see** something like: ``` [VideoHelperSuite] Registered X nodes... ``` --- ### 🧹 If you want to bypass it right now If you're blocked and want to continue testing the rest of your graph: - **Open the graph UI** - **Delete node 48** (`VHS_VideoCombine`) - Connect the output of node 8 to a `SaveImage` node or `PreviewImage` - Click **Queue Prompt** This will skip video combining entirely and let the rest of your workflow run. --- Would you like me to send you a cleaned version of the workflow `.json` file without node 48 so it loads and runs right away?

zsh: no matches found: imageio[ffmpeg]

The error: ``` zsh: no matches found: imageio[ffmpeg] ``` ...happens because `zsh` tries to expand `[ffmpeg]` as a **glob pattern**, like a filename match — but there’s no file named `imageio[ffmpeg]`, so it fails. --- ### ✅ Fix it by quoting the package name: ```bash pip install 'imageio[ffmpeg]' ``` Or, if you want to install everything needed for `ComfyUI-VideoHelperSuite` video support: ```bash pip install 'imageio[ffmpeg]' moviepy av opencv-python-headless ``` --- ### 🧠 Explanation: In `zsh` (and sometimes `fish`), characters like `[` and `*` are interpreted unless **quoted**. Always wrap such package names in single or double quotes when using extras like `[ffmpeg]`. --- Let me know if you want a full requirements.txt for ComfyUI with video support and optional nodes bundled.

got prompt invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#48'", 'extra_info': {}}

The error you're seeing: ``` invalid prompt: {'type': 'invalid_prompt', 'message': 'Cannot execute because a node is missing the class_type property.', 'details': "Node ID '#48'"} ``` ...means **Node #48** in your workflow (the `VHS_VideoCombine` node) is **missing or broken** — likely because its code didn't load correctly at startup. --- ### 🔍 Why this is happening: Looking back at your logs: ``` ModuleNotFoundError: No module named 'cv2' ... IMPORT FAILED: /ComfyUI/custom_nodes/ComfyUI-VideoHelperSuite ``` So, the `ComfyUI-VideoHelperSuite` node (which contains `VHS_VideoCombine`) **didn't load**, because `cv2` (OpenCV) is missing. --- ### ✅ Fix steps: 1. **Install OpenCV** (required by VideoHelperSuite): ```bash pip install opencv-python-headless ``` Or, if you want GUI features (not usually needed for ComfyUI): ```bash pip install opencv-python ``` 2. **Restart ComfyUI** completely after installing. 3. Verify it's loaded by checking for `VHS_VideoCombine` in the node list. --- ### 🔄 Alternative quick fix: If you're **not using** `VHS_VideoCombine` actively, you can delete Node #48 from your workflow JSON to remove the error. But if you **do need it**, the proper fix is just: ```bash pip install 'imageio[ffmpeg]' opencv-python-headless ``` --- Let me know if you want help editing your JSON to remove the broken node or rebuilding a working video export workflow.
