agent: ai_agents

When does this happen?

IF Importing from langchain.chains fails with ModuleNotFoundError: No module named 'langchain_core.tracers.langchain_v1'.

How others solved it

THEN Downgrade langchain-core to version 0.1.4 (e.g., `pip install langchain-core==0.1.4`) to align with the installed langchain and langchain-community versions. This resolves the missing tracer module that caused the import failure.

pip install langchain-core==0.1.4
