"403 Invalid API Token: caveat must be an array" when using hatch publish

[mcarans]

Describe the bug
I receive the following error when using hatch publish for a package that has been published fine many times before:

Error uploading to repository: https://upload.pypi.org/legacy/ - Client error '403 Invalid API Token: caveat must be an array' for url 'https://upload.pypi.org/legacy/'

I have not changed anything to do with the publishing (HATCH_INDEX_USER and HATCH_INDEX_AUTH are the same and I haven't touched pyproject.toml).

Expected behavior
Package is published

To Reproduce
Publish a package using hatch in a GitHub Actions workflow

My Platform
I'm running the publish workflow in GitHub Actions. You can see it here if it's any help:

This should now be resolved.
