Confirmation

• I have read and followed all instructions in README.md.
• I am using 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 every relevant configuration, setting, and environment variable used in my setup.
• I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
• I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
• Start with the initial platform/version/OS and dependencies used,
• Specify exact install/launch/configure commands,
• List URLs visited, user input (incl. example values/emails/passwords if needed),
• Describe all options and toggles enabled or changed,
• Include any files or environmental changes,
• Identify the expected and actual result at each stage,
• Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

1. After a user submits a chat request, the Pipelines should generate [DEBUG] Received request] logs in OpenWebUI, indicating that data is being sent to Langfuse. code line 123
2. The Langfuse Dashboard should display corresponding traces or events (e.g., input/output, model name, latency metrics).
3. If there is a connection failure or authentication error, OpenWebUI should raise [ERROR] logs to alert users instead of failing silently.
4. The integration should work seamlessly after updating OpenWebUI, without requiring manual code changes or reconfiguration.

Actual Behavior

1. After a user submits a chat request in OpenWebUI, no [DEBUG] Received request logs are generated in the Pipelines code. code line 123
2. The Langfuse Dashboard does not show any traces or events, even though the same credentials and host work when tested manually.
3. No errors are logged in OpenWebUI or Langfuse services, making it unclear why the integration fails.

Steps to Reproduce

1. Use openwebui v0.6.10
2. Connect to langfuse
3. upgrade openwebui v0.6.10 to openwebui v0.6.11

All the sever are deployed in docker.

I know it's closed but @UnknownX1 did you manage to resolve this? Any tips??

I had mine working before and forwarding fine, but something somwwhere has broken it and i'm getting exactly what this issue describes - no error logs, just 0 items in queues.

Even intentionally wrong secrets or urls do not give any error logs.

I have the same issue @UnknownX1. How can solve?

In my case, I need to re-enable the filter module (specifically, the langfuse_filter_pipeline model) via Admin Panel → Settings → Models.
