Can't make the extension work

I can't figure out why the extension doesn't work for me. I've looked at the issues related to that but nothing resolves my problem... I set my instance URL to gitlab.com and created my private access token with all the rights for it, pasted everything in the configuration but when I try to do an action it says: "GitLab Workflow: No project or pipeline found." I also don't use a multi-root workspace.

Here are the logs in the console:
