Harbor integration does not display repositories of my harbor's project

Hi,

I enabled the Harbor feature on a self-hosted Gitlab instance 15.x.
Heading to gitlab-instance-15957a72/firstproject/-/harbor/repositories/ does not display my harbor’s project repositories.
Even though clicking on “test connection” was successful.

I only see “shao/flinkx”, “shao/flinkx1”, and “shao/flinkx2”.

Any idea what may be the problem?
