It actually failed:

    raise ValueError(f"{error}\n{summary}") from None
ValueError: invalid pyproject.toml config: `project.license`.
configuration error: `project.license` must be valid exactly by one definition (2 matches found):

    - keys:
        'file': {type: string}
      required: ['file']
    - keys:
        'text': {type: string}
      required: ['text']

@hugovk: Can you help me to figure out what went wrong?

Ah,

• https://github.com/pypa/gh-action-pypi-publish/releases/tag/v1.12.4

17 commits to unstable/v1 since this release

So it's not included in @release/v1... ?

... but your project also uses @release/v1:

• https://github.com/hugovk/humanize/blob/6427174e3300a9bbb59558ea47a6fc7b03cb3015/.github/workflows/release.yml#L85-L86

You're using setuptools as the build backend:

setuptools doesn't yet support the new PEP 639 licence metadata, but they're working on it right now:

pypa/setuptools#4829

I'm using hatchling:

https://github.com/hugovk/humanize/blob/6427174e3300a9bbb59558ea47a6fc7b03cb3015/pyproject.toml#L2

Reverted until setuptools is updated or switching to hatchling

• Fix: Revert "Replace deprecated classifier with licence expression (PEP 639)" #2202
