Original Pull Request: https://github.com/langchain-ai/langgraph/pull/4924

State: closed
Merged: Yes


This adds support for passing in a custom langchain tracer to the runs client (specifically create and wait) which gets passed directly into the api.

Only adding this for the js sdk because this is meant to be internal only and the context that we are using this in only uses the js sdk.

Waiting to implement the api updates until its more clear how this should actually get traced.
