When does this happen?
IF ChatVertexAI raises PydanticUndefinedAnnotation for 'SafetySetting' when using pydantic >= 2.9.1
How others solved it
THEN Downgrade pydantic to version 2.9.0 to resolve the missing forward reference. This is a temporary workaround until the langchain-google-vertexai package updates its dependency.
pip install pydantic==2.9.0
