Same issue.

I've double check the response content-type is appropriate. I am using vllm with openai api. How did you fix this issue? @StruggleJia

There's one solution, execute the below setup before start open-webui serve:
export ENABLE_OLLAMA_API=false
export OPENAI_API_BASE_URL=http://0.0.0.0:11434/v1
