What this warning trying to say? "LangSmith received circular JSON. This will decrease tracer performance."

[WARNING]: LangSmith received circular JSON. This will decrease tracer performance.
Context: Serializing outputs for multipart ingestion of run with id: b5639254-5eb1-464d-a197-84e52f637f03

I started seeing this warning when I upgraded the following dependencies:

    "@langchain/core": "^0.3.57",
    "@langchain/langgraph": "^0.2.74"

Could anyone who has experienced this please elaborate?
