/tmp/build-env-ltwgiw2r/lib/python3.10/site-packages/setuptools/config/_apply_pyprojecttoml.py:82: SetuptoolsDeprecationWarning: `project.license` as a TOML table is deprecated
  !!
  
          ********************************************************************************
          Please use a simple string containing a SPDX expression for `project.license`. You can also use `project.license-files`. (Both options available on setuptools>=77.0.0).
  
          By 2026-Feb-18, you need to update your project and remove deprecated calls
          or your builds will no longer be supported.
  
          See https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license for details.
