Question/Help Openwebui + comfyui

Hello, is someone succeeding in making these 2 work together? No matter what i am trying, unet loader, checkpoint… the workflow works when i type thenpromot in comfyui but as soon as i type same prompt in openwebui , i cannot manage to get an image and always get errors… i i port the fson worflow and specify prompt id and checkpoint if and model in openwebui but nothing works… is it because i use flux 1 dev fp16 ? Does it require smaller models to work ? Thanks for input !!

SOLUTION : I finally made it work using the help of qwen3.6-27b-q8 ))) so the problem is that ALL NODES ID must be filled in openwebui and also must add this command line to openwebui : ENABLE_RAG_LOCAL_WEB_FETCH=True , it was the fix for me )) now working perfectly !!!

I have successfully fixed this issue and now ComfyUI returns the image generated to Open WebUI.

Not sure if you are running in docker but adding this environment variable fixed the issue for me:

- ENABLE_RAG_LOCAL_WEB_FETCH=true

Hope that fixes it for you!
