LangFuse is incredibly out of date

This project has pinned LangFuse to an unbelievably old version:
langfuse = "^2.43.3"

This is a major version behind. There are numerous bugs fixes and improvements in the new version. For example, the version that this is pinned to will have problems interacting with Anthropic, the best coding model on the market. 

I recommend you bump the version to the latest.
