Creating pending Trusted Publisher for Gitlab project gives 404

[sebastianw]

Describe the bug

Trying to create a pending trusted publisher for a Gitlab hosted project only returns a 404 error. Trying it with Github as Trusted Publisher works as expected.

Expected behavior

A pending publisher is created.

To Reproduce

Go to Account Settings -> Publishing and try to create a pending publisher for Gitlab.

My Platform

MAcOS 15.6.1 with Firefox 144.0.2

Additional context

Screenshots follow:

Same here (Firefox 144.0.2, Ubuntu 24.04)

I also received a 404 not found page when I wanted to associate a GitLab publisher to an existing PyPI project (plasmid-bin-bench) previously associated with before (I removed by error the association).

Thank you @miketheman and @di for the fixes.

I am still not able to add a GitLab trust publisher to an existing PyPI.org project.
Perhaps I have to wait the modifications to be fully deployed on PyPI.org.

Hi @vepain ! The fix should be fully deployed to production now, a good browser refresh should help.

Thanks @miketheman !

Even after refreshing my browser (closing it, re-launching) I am still not able to add it...
I will retry tomorrow, and temporarily use twine upload manually.

I think this might be a different problem. I can now create a pending publisher but I can't add a GitLab trusted publisher to an existing project.

I've created #18999 for this.
