Error on 'bash[migrate gitlab-rails database]': Update to 15.0.0 from 14.x.x

Good evening, I tried updating my dockerized Gitlab to 15.0.0 and I am encountering the following error:


Recipe: gitlab::database_migrations

  * rails_migration[gitlab-rails] action run

Running handlers:
There was an error running gitlab-ctl reconfigure:

rails_migration[gitlab-rails] (gitlab::database_migrations line 51) had an error: Mixlib::ShellOut::ShellCommandFailed: bash[migrate gitlab-rails database] (/opt/gitlab/embedded/cookbooks/cache/cookbooks/gitlab/resources/rails_migration.rb line 16) had an error: Mixlib::ShellOut::ShellCommandFailed: Command execution failed. STDOUT/STDERR suppressed for sensitive resource

Running handlers complete
Cinc Client failed. 13 resources updated in 43 seconds

And the docker container restarts.

Now I read in some other posts to just execute

# gitlab-rake gitlab:background_migrations:finalize[ProjectNamespaces::BackfillProjectNamespaces,projects,id,'[null\,"up"]']

but that ends in the following error:

rake aborted!

Any ideas on how to get more information or how to fix this is greatly appreciated!
