Wan Vace reference to video template workflow, path problems

[ReinerBforartists]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

When i save a workflow with which i just have created a video, then i expect the workflow to load fine afterwards. Since this workflow has already worked.

Actual Behavior

When i load the Wan Vace reference to video template , change the lora to another path, and load this working workflow afterwards into a new comfyUI instance, then i get a warning that the lora is missing. Which it is not. It is just in another folder, a sub folder in the loras folder. And the workflow works of course fine.

Steps to Reproduce

• Load the Wan Vace Reference to Video workflow.

Move the loras to a subfolder in the loras folder. The reason why i do this is that i have a ton of different models, and so a ton of different files. And at one point you completely loose track which file belongs to what model and what workflow.

Change the lora path so that it points to the lora in the subfolder

Run the workflow. It will work just fine.

Save the workflow.

Now reload the workflow that you just have saved. Despite the workflow has everything in place and has just worked fine before a few moments, you will get a warning about missing files.

It will be fixed in the next version of the frontend (1.22.0)! The missing models warning won't show up if the selected file in the node is different from the model name in the metadata: Comfy-Org/ComfyUI_frontend#4021. Thank you for the report.

If you'd like you can use the latest version of the frontend by using

--front-end-version Comfy-Org/ComfyUI_frontend@latest
