I have this error also- just upgraded CrewAI (on Linux) and got this validation error (was working before)

Starts with this warning also: module_import.py:87: LangChainDeprecationWarning: Importing GuardrailsOutputParser from langchain.output_parsers is deprecated. Please replace the import with the following: from langchain_community.output_parsers.rail_parser import GuardrailsOutputParser warnings.warn(

And then the error: main.py", line 175, in __init__ self.__pydantic_validator__.validate_python(data, self_instance=self) pydantic_core._pydantic_core.ValidationError: 1 validation error for Task expected_output Field required [type=missing, input_value={'description': 'You will...o produce perfect code)}, input_type=dict] For further information visit https://errors.pydantic.dev/2.7/v/missing

you didnt add the expected output in the code task = Task (description="""what is 3 + 5""", agent = general_agent, expected_output=' ')

[mustangs0786]

can you give a sample example expected_output to put here thanks
