Hello,

When using output_pydantic I’m having the following error:

ERROR: Error in crew execution: Failed to convert text into a Pydantic model due to error: 'NoneType' object has no attribute 'function_calling_llm'
2025-03-30 13:07:06,792 - __main__ - ERROR - Error in proposal generation: Failed to convert text into a Pydantic model due to error: 'NoneType' object has no attribute 'function_calling_llm'

Here one of my class.

class Email(BaseModel):
    subject: str
    body: str
    greeting: str
    signature: str

Any hint?

Regards,

I suggest you provide more context so someone can weigh in.

If this Pydantic model is being used in the output_pydantic of a task, please provide the task (or a simplified version of it).

It was related to the model in use, don’t support function calling.

Thanks,
