I am new to GitLab CI/CD's and I wonder what my pipeline is doing. The syntax is correct but the job keeps failing, but I don't know why and would like to check the trace. When viewing the job trace it says 'This job does not have a trace'. The same is happening if I view the job logs. There is just the text 'no job log'.
Every single job I ran has no trace, so I suspect it is a configuration issue in our self-hosted gitlab-runner. I found posts with the same issue but without any solution. I tried to run the gitlab-runner debug mode but its output is of no use.
I am using a shell executor and installed docker on the gitlab-runner.
Edit: I coincidently got a job log once, but rerunning the job gives me the same "no job log" / "This job has no trace".
