When does this happen?

IF Using DocArrayInMemorySearch with VectorstoreIndexCreator raises a Pydantic ValidationError because pydantic v2 lacks required 'text' and 'metadata' fields.

How others solved it

THEN Downgrade pydantic to version 1.x (e.g., 1.10.13) to ensure compatibility with LangChain's DocArray integration. Run 'pip install --upgrade pydantic==1.10.13' in your environment.

pip install --upgrade pydantic==1.10.13
