Model fix

add default value for extra_fields

[hall-b]

Bad idea to initialize directly with a dictionary.

Better do: extra_fields: Optional[dict] = Field(default_factory=lambda: dict())

[yannicschroeer]

Agreed, default values for dictionaries should either be a factory method or None (Which it was before) due to their mutability. Anyway, why is a default value necessary?

[hall-b]

I guess if the value is not initialized and thus equal to None, it will raise an error here when trying to set a value

Or just Field(default_factory=dict)

I'd prefer this. No need for a lambda
