pydantic arbitrary_types_allowed=True error

[mathigatti]

I got this error, it was fixed by updating gradio though, I'm sharing it in case it's useful for someone

Fix command: pip install -U gradio==4.43.0

Error message

    return self._unknown_type_schema(obj)
  File "/usr/local/lib/python3.10/dist-packages/pydantic/_internal/_generate_schema.py", line 415, in _unknown_type_schema
    raise PydanticSchemaGenerationError(
pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'starlette.requests.Request'>. Set arbitrary_types_allowed=True in the model_config to ignore this error or implement __get_pydantic_core_schema__ on your type to fully support it.

If you got this error by calling handler(<some type>) within __get_pydantic_core_schema__ then you likely need to call handler.generate_schema(<some type>) since we do not call __get_pydantic_core_schema__ on <some type> otherwise to avoid infinite recursion.
