Field required [type=missing, input_value={}, input_type=dict]" for locale, has_enough_context, thought, and title in Plan model

[Vy-Bui17]

Hi guys, can any of you take look at this error. Looks like Planner cannot generate the full report because LLM model does not return valid response.

Therefore, the pydantic throw validation error:

pydantic_core._pydantic_core.ValidationError: 4 validation errors for Plan
locale
Field required [type=missing, input_value={'error': 'Invalid charac...char 2279): "\u007f".'}, input_type=dict]
