Do not merge before Ghaf release 24.12 is out. It is too late to make changes to test automation before the release.

I will add the bug-label here until the test-automation has been fixed to support this pr. We don't really have an accurate label for this situation.

Test-automation has been checked and it works with this pr. This can now be merged.
