Exception in ASGI application

[barantt]

When I tried to use the sample image to experience this function, I got the following error

ERROR:    Exception in ASGI application
Traceback (most recent call last):
  File "/usr/local/miniconda3/envs/paints_undo/lib/python3.10/site-packages/pydantic/type_adapter.py", line 270, in _init_core_attrs

AttributeError: __pydantic_core_schema__

During handling of the above exception, another exception occurred:

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.
