pypi 400 error on hatch publish

[cornhundred]

Hi I am unable to publish my Python library to PyPI using the latest version of hatch and I think the issue is related to the version of the package metadata (2.3 vs 2.4) - any help would be appreciated

Running hatch build works

(celldega_3.9) ➜  celldega git:(main) hatch build

but I am seeing this error when I try to publish to PyPI

$ hatch publish
