THEN Downgrade langchain, langchain-core, langchain-community, and langchain-openai to versions before the breaking change (e.g., langchain 0.2.16, langchain-community 0.2.17, langchain-core 0.2.41, langchain-openai 0.1.25). Alternatively, add an explicit Pydantic v2 BaseModel Input class to the tool's args_schema to override the empty schema.

# Downgrade approach
pip install langchain-community<0.3 langchain<0.3
pip install langchain-core<0.3
pip install langchain-openai<0.2
