Demo doesn't work: TypeError: issubclass() arg 1 must be a class

[ndfriedman]

I am getting the following error: File "pydantic/fields.py", line 638, in pydantic.fields.ModelField._type_analysis File "/usr/local/lib/python3.10/typing.py", line 1157, in subclasscheck return issubclass(cls, self.origin) TypeError: issubclass() arg 1 must be a class.

I'm running the code on "pythonanywhere" with python 3.10.5.

Thanks for the help!

The problem in pydantic lib, try change version (for ex. pip install --upgrade pydantic==1.10.12)
