I am trying to run testJob in GitLab CI/CD and I keep ending up with this error, I have ensured that the APP_KEY is set in the CI/CD variables and echoed it to see if it’s consistent with my expectation, and it was. I don’t know where I am missing it. I did read around related here, here, documentation, etc… but I have not availed a solution Can anyone help with this issue?
