This still seems to happen on Python 3.9.9 - I'm guessing this is a problem with Pydantic, and not this library though.

Yup, it's a pydantic issue.

But this issue should not be present anymore because fastapi-pagination version 0.9.1 contains a workaround.

Maybe I am doing completely wrong here - using the latest version, all my pytest fail with the error above, but the code will run. The only way to fix the pytest errors is by using the latest master version of pydantic, but that introduces other breaking changes in my code and breaks while running.

I'm using a custom page setup (basic page with an added total pages parameter), not really sure what I'm missing here.
