Please describe the issue that you are experiencing
When using GHA to auto-publish to TestPyPI, enabling job verbose mode showed the following error:
body may not contain duplicate keys
This error message was very confusing.
I resolved this by fixing the repository URL to have a forward slash on the end of the URL.
Wrong:
repository-url: https://test.pypi.org/legacy
Correct:
repository-url: https://test.pypi.org/legacy/
Please list the steps required to reproduce this behaviour
Create a GHA pypi auto-publish workflow using this exact workflow code.
Remove the forward slash at the end of the TestPyPI URL.
Then push a commit to trigger the auto-build and auto-publish actions.
Anything else you'd like to mention?
