At what exercise or lab have you encountered that issue ?
I am studying DO447 too. So far, the only bug I have encountered was at guided exercise 3.2 where the following error occured:
[student@workstation ~]$ lab task-escalation start
Adding content to git repo................. FAILED
Running the same command again with sudo turned out to be a valid workaround.
The Project creation in guided exercise 9.2 gives the output as follow:
Verification in /var/lib/awx/projects directory on tower server
and in /var/opt/gitlab/git-data/repositories/git directory on utility server confirm that.
However in the review lab, the content is successfully added in the git repo and all is working fine. The TEST repo is available in utlity server (gitlab)
I encounter no issue with that guided exercise 9.2. Maybe it's been fixed in the meantime.
Otherwise, please check:
Then trigger the SCM update again.
Missing one of those requirements gives the symptom you describe.
EDIT: Your statement that lab 9.5 works fine means that your student-git credential is correct. As you don't see the git repository content on the utility server (I do), check that you have succesfully executed the lab start script :
[student@workstation ~]$ lab provision-project start
Otherwise, it only means that the lab has been fixed in the meantime
