The first category is errors or unexpected behavior caused by the syntax and logic in .gitlab-ci.yml, the primary CI/CD configuration file. The second category involves limitations or misconfigurations in the runner infrastructure used to run CI/CD jobs. We will address each of these categories in turn.
