I have read and followed all the instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.
Expected Behavior:
Every prompt that user makes or that Open WebUI makes on behalf of a user (title and tags generation prompts) should include user parameter in a request, so that we can track the costs per user in LiteLLM/Langfuse.
Actual Behavior:
Only user prompts include user parameter. Title and tags generation prompts are registered in LiteLLM/Langfuse without user.
Description
Bug Summary:
User parameter is not passed for title and tags generation prompts request.
Reproduction Details
Steps to Reproduce:
Deploy Open WebUI, LiteLLM and Langfuse. Configure LiteLLM to use Langfuse for logging and Open WebUI to use LiteLLM as OpenAI API endpoint.
