Expected Behavior

The Text Encode Qwen Image Edit node in Comfy Desktop should load and work normally without showing errors (not highlighted in red).

Actual Behavior

When I add the Text Encode Qwen Image Edit node, it appears highlighted in red and does not function. Other nodes work as expected. I’m using Comfy Desktop with ComfyUI version v0.3.50 (according to settings), so it should be up to date.

Image Image Image

Steps to Reproduce

Open Comfy Desktop (ComfyUI v0.3.50).

Add a Text Encode Qwen Image Edit node to the workflow.

Observe that the node is highlighted in red and fails to work.

Originally created by @manassm on GitHub (Aug 19, 2025). Original GitHub issue: https://github.com/Comfy-Org/desktop/issues/1257 ### App Version <img width="1920" height="1009" alt="Image" src="https://github.com/user-attachments/assets/e9aa376c-de21-447f-a00b-f5d73e5d5432" /> ### Expected Behavior The Text Encode Qwen Image Edit node in Comfy Desktop should load and work normally without showing errors (not highlighted in red). ### Actual Behavior When I add the Text Encode Qwen Image Edit node, it appears highlighted in red and does not function. Other nodes work as expected. I’m using Comfy Desktop with ComfyUI version v0.3.50 (according to settings), so it should be up to date. <img width="1920" height="1009" alt="Image" src="https://github.com/user-attachments/assets/88d5764c-3d2c-4b71-89f3-1f9bbcb9c227" /> <img width="1920" height="1009" alt="Image" src="https://github.com/user-attachments/assets/bf864ead-1efd-4aa4-92d1-eeb66b8e16c0" /> <img width="1920" height="1009" alt="Image" src="https://github.com/user-attachments/assets/64fe7e36-d2e5-4068-8778-bbabbd290dfe" /> ### Steps to Reproduce Open Comfy Desktop (ComfyUI v0.3.50). Add a Text Encode Qwen Image Edit node to the workflow. Observe that the node is highlighted in red and fails to work. ### Debug Logs ```powershell extra search path custom_nodes C:\Users\SEPHiA\Documents\ComfyUI\custom_nodes Adding extra search path download_model_base C:\Users\SEPHiA\Documents\ComfyUI\models Adding extra search path custom_nodes C:\Users\SEPHiA\AppData\Local\Programs\@comfyorgcomfyui-electron\resources\ComfyUI\custom_nodes Setting output directory to: C:\Users\SEPHiA\Documents\ComfyUI\output Setting input directory to: C:\Users\SEPHiA\Documents\ComfyUI\input Setting user directory to: C:\Users\SEPHiA\Documents\ComfyUI\user [START] Security scan [DONE] Security scan ## ComfyUI-Manager: installing dependencies done. ** ComfyUI startup time: 2025-08-19 13:35:45.856 ** Platform: Windows ** Python version: 3.12.4 (main, Jul 25 2024, 21:57:00) [MSC v.1929 64 bit (AMD64)] ** Python executable: C:\Users\SEPHiA\Documents\ComfyUI\.venv\Scripts\python.exe ** ComfyUI Path: C:\Users\SEPHiA\AppData\Local\Programs\@comfyorgcomfyui-electron\resources\ComfyUI ** ComfyUI Base Folder Path: C:\Users\SEPHiA\AppData\Local\Programs\@comfyorgcomfyui-electron\resources\ComfyUI ** User directory: C:\Users\SEPHiA\Documents\ComfyUI\user ** ComfyUI-Manager config path: C:\Users\SEPHiA\Documents\ComfyUI\user\default\ComfyUI-Manager\config.ini ** Log path: C:\Users\SEPHiA\Documents\ComfyUI\user\comfyui.log [ComfyUI-Manager] Failed to restore comfyui-frontend-package expected str, bytes or os.PathLike object, not NoneType Prestartup times for custom nodes: 2.3 seconds: C:\Users\SEPHiA\AppData\Local\Programs\@comfyorgcomfyui-electron\resources\ComfyUI\custom_nodes\ComfyUI-Manager Checkpoint files will always be loaded safely.

Hi @manassm! I'm Dosu and I’m helping the desktop team.

The error with the Qwen Image node ("missing the class_type property" and highlighted in red) means ComfyUI failed to load or register the node correctly. This usually happens if the custom node's Python module doesn't export NODE_CLASS_MAPPINGS properly, if there was an import error, or if required dependencies are missing or incompatible. In ComfyUI, nodes must be registered with NODE_CLASS_MAPPINGS for the backend to recognize them, and any failure here will cause the node to break in the UI docs.comfy.org.

Common causes include: using an outdated ComfyUI version (the modal suggests this), missing or broken dependencies, or a bug in the custom node code. The desktop app itself only surfaces backend errors—it doesn't fix or validate node internals docs.comfy.org.

Recommended steps: update ComfyUI to the latest Development (Nightly) version (not just Desktop), update all custom nodes, and manually install dependencies for the Qwen node by running pip install -r requirements.txt in its folder if needed docs.comfy.org. If the issue persists, try disabling custom nodes, resetting the virtual environment, or doing a clean reinstall github.com/Comfy-Org/desktop/issues/1216.

If you see 404 errors for Qwen-Image PNGs, that means the workflow is referencing files that aren't present—make sure all required assets are in the correct input folder.

Let me know if you need more details on any of these steps.

@webfiltered commented on GitHub (Aug 19, 2025):

The workflow you're trying to use requires some custom nodes are installed. There's a button on the first error message to open manager and install them.

I'd recommend trying the help channel in Discord for general support; you may experience long delays between replies on GitHub issues.

Image Thank you for your help. I tried clicking it but didn't respond at all as if the button was disabled. I am guessing I will need to wait for the stable release to be pushed, hopefully soon. Thank you.
