[syou6162]

The following warning message was outputting a link that was not valid, so it has been corrected to a valid link.

/Users/yasuhisa.yoshida/.cache/pre-commit/repoclpuwaei/py_env-python3.10/lib/python3.10/site-packages/isort/settings.py:343: UserWarning: A custom settings file was specified: /Users/yasuhisa.yoshida/my_project/pyproject.toml but no configuration was found inside. This can happen when [settings] is used as the config header instead of [isort]. See: https://pycqa.github.io/isort/docs/configuration/config_files/#custom_config_files for more information.
