When does this happen?

IF When using Langfuse v3 Python SDK with LiteLLM, a TypeError occurs during callback initialization due to an unexpected keyword argument 'sdk_integration'.

How others solved it

THEN Downgrade the Langfuse Python SDK to version 2 (e.g., `pip install langfuse==2.*`) to ensure compatibility with LiteLLM. Monitor for future LiteLLM updates that add support for Langfuse v3.

pip install langfuse==2.58.0
