This worked yesterday with another repo that had mostly identical properties, but for this repo, the save button generates a malformed request, and triggers a nonsensical validation warning. It is a private repo, attempting to move from a public project to a private project.
Just to confirm - you are changing the project for the repository within the same workspace?
I have tested this on my end and was unable to reproduce the issue - I have a private repository within a public project and can seamlessly switch through the various projects and save at the end without an error message.
Are you able to clear your browser cache/attempt this in a different browser (or in Incognito mode if using Chrome)?
