Do you have a volume mapping for pipelines?

[attilaszasz]

@bannert1337, I experience the same problem. I have a volume mapping, but it's not the same as the open-webui volume. Should it be?

My volumes in docker-compose:

volumes:
  open-webui: {}
  pipelines: {}

This is likely an issue from the pipeline code in question here not implementing the correct initialization/startup logic.

[attilaszasz]

Yep, I fixed for the Google pipeline, the same fix should work here, but I don't use litellm to be able to test it.

@attilaszasz thanks again for that, I've applied the same in #210 to fix LiteLLM manifold. Would appreciate if someone here would test that before merging. Nevermind, we YOLO-merge :P
