Trusted publishing gives a syntax error

[vtnate]

I'm updating from using an rsa token to using trusted publishing, and I'm getting this error during deployment to pypi:

Checking dist/ThermalNetwork-0.2.3rc5-py3-none-any.whl: FAILED
ERROR long_description has syntax errors in markup and would not be
rendered on PyPI.
line 27: Error: Unexpected indentation.

There is no long_description in my repo, and this error didn't get raised when using the token. I don't know how to get trusted publishing to work as expected. Is the source of this error anything you know of?

My current workflow file is: https://github.com/NREL/ThermalNetwork/blob/fix-packaging/.github/workflows/release.yml

This is not related to secretless publishing. It's just that the dist you're trying to upload doesn't provide long description. The action checks the dists by running twine check --strict. It's generally recommended to do this early in your CI pipeline so that it raises the red flag earlier.

You can ask the action to skip that metadata verification check: https://github.com/marketplace/actions/pypi-publish#disabling-metadata-verification. Though, the proper solution is to fix your dist's metadata. PyPI may reject your uploads when the meta is corrupted more seriously.

Thank you for your reply! For posterity, it turns out that pypi was not parsing my readme.md as markdown (despite doing so for several releases prior). When I explicitly declared my readme as a markdown file in pyproject.toml, all was well again.
