Reproduction Details
ComfyUI works fine from its web interface.
Steps to Reproduce:
Click the image icon on the response from a model
Additional Information
Seems to be the way the request is being made to comfyui and the API signature doesnt match.
Here is a screen shot of the open web-ui configuration of comfyui.
Here is a image of comfyui working:
@pkeffect commented on GitHub (Feb 7, 2025):
You first need to make sure you specifically exported your comfyui workflow as workflow api. There are 2 options to export. Second, you need to fill the values in for your nodes to match the nodes listed in your workflow.
