To Reproduce
I'm using Poetry (version 1.3.2) and mypy version (1.4). Moreover I'm using mypy's plugin for pydantic defined in pyproject.toml:
# pyproject.toml
[tool.mypy]
ignore_missing_imports = true
strict_optional = true
show_error_codes = true
plugins = ['pydantic.mypy']
The pydantic version I'm using is 1.10.7. To run mypy, I use the following command: poetry run mypy app, where app is the folder containing my application code.
Please note, that all works fine for mypy version 1.3 without any errors.
