This error comes from pydantic plugin, not from mypy itself - most likely a compatibility problem. You're certainly missing relevant part of mypy.ini or pyproject.toml where the plugin is enabled. Are you using the latest pydantic version? Does this happen with latest and master mypy?

Duplicate of #17671 / pydantic/pydantic#10129. This should be fixed in pydantic 1.10.16+. Thanks!
