[lure8225]

Summary

When importing credentials the current implementation fails because it tries to prevent re-owning although the user already owns the credential.

Hey @lure8225,

Thanks for the PR, We have created "GHC-1265" as the internal reference to get this reviewed.

One of us will be in touch if there are any changes needed, in most cases this is normally within a couple of weeks but it depends on the current workload of the team.

Now properly set up devcontainer which I should have from the start. Tests fixed and passing locally now. Is there a good way to run single tests instead of just running pnpm run test:backend?
