I'm getting the following error at the following line
parser = PydanticOutputParser(pydantic_object=BusinessNames)

ValidationError: 1 validation error for PydanticOutputParser
pydantic_object
subclass of BaseModel expected (type=type_error.subclass; expected_class=BaseModel)

Hi @godfreynolan , this has been fixed.

Pydantic in the examples is now locked in at v1, until LangChain fully migrates to v2 of Pydantic.

Thanks for spotting this!
