+## No report artifact is created
+
+With certain Runner configurations, the Code Quality scanning job may not have access to your source code.
+If this happens, the `gl-code-quality-report.json` artifact won't be created.

+- Apply the [community workaround in issue 32027](https://gitlab.com/gitlab-org/gitlab/-/issues/32027#note_1318822628) if you wish to continue using Docker socket binding.
