Is that using a default workflow? Are there any errors in the ComfyUI console?
Default workflow, yep.
Its throwing ComfyUI Error: ComfyUI execution error: and then calling "ComfyUI\\resources\\ComfyUI\\execution.py" with a large string of text.
I have extremely minimal coding knowledge so I can't pinpoint any other errors beyond the "No Images in ComfyUI output". It almost seems like the mod isn't asking ComfyUI to generate anything?
That stack trace looks similar to one I saw yesterday. See the troubleshooting section in the README and try the last thing mentioned:
I'm seeing an error that looks like "[Errno 22] Invalid argument
This usually indicates a problem with ComfyUI's configuration. As discussed in this issue, try changing the port that ComfyUI is using (in the Server-Config settings).
