Thank you very much for the excellent work of the author！！ What is the reason for this problem? When I open the web UI page and click on upload soil or audio, the following error appears： ERROR: Exception in ASGI application Traceback (most recent call last): File "/home/sjy/anaconda3/envs/mofa/lib/python3.10/site-packages/pydantic/type_adapter.py", line 270, in _init_core_attrs self._core_schema = _getattr_no_parents(self._type, 'pydantic_core_schema') File "/home/sjy/anaconda3/envs/mofa/lib/python3.10/site-packages/pydantic/type_adapter.py", line 112, in _getattr_no_parents raise AttributeError(attribute) AttributeError: pydantic_core_schema

During handling of the above exception, another exception occurred:

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() 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.

for my case, downgrade the fastapi==0.112.4 solve the problem
