Thank you for reporting this! It seems to be an issue between FastAPI and Pydantic that is breaking the project. We're looking into it…

The issue seems to be that FastAPI compatibility with Pydantic V2 is not quite there yet. If you force reinstall V1 of Pydantic, that should get you up and running with the example while FastAPI gets it sorted out. We are working on filing a bug with them, but they've already acknowledged the problem in their discussion so they are probably already working to fix it.

Here's the command to force install the older version of Pydantic with pip:

pip install --force-reinstall -v "pydantic==1.10"
