Gitlab - Project cannot be transferred, because tags are present in its container registry

Question

Project cannot be transferred, because tags are present in its container registry

I am encountering the above error when I try to transfer my git repository to a group.

I have checked in Repository/Tags but there are none. I have also checked in CI/CD tabs and there's nothing outstanding there either. So I'm wondering what tags is it referring to.

I am currently using Netlify for my frontend hosting and Heroku for my backend hosting.

Could either of these be applying some tags that I can't see/find?

Is my only option to export the project?

Issue 33301 mentions:

the only way to move a project with containers in the registry is to first delete them all.

Meaning delete the container tags in the registry (not the repository or CI/CD)

• Navigate to sidebar menu Package->Container Registry on a project where Container registry is enabled
• Click on the button "Remove Tag"

(since GitLab 12.3, Sept. 2019, you can delete the tags you want)
