Gitlab:doctor:secrets: failures: analyze

We’ve got notifications about issues with our secrets after the upgrade to 13.1.11 by gitlab:doctor:secrets.
But we updated our instance from 11.11.3 and don’t know when issues appeared.
Is there any way to check secrets before 13.1.1 or how to get more information about what was affected (projects/types of credentials)?

Gitlab:doctor:secrets output:

For example: What is ProjectImportData[2]? Where I can find information about it (is it a repository or any token?)?

Additional: I’ve tried old tools/script: https://gitlab.com/snippets/1876342/raw

additional check

And there aren’t any errors.

Thank you for your help,
Kind regards,
