@come-nc Hello, would you mind review my PR ? Thanks !

[come-nc]

self::FAILURE should be used instead of return 1 for consistency.

[GreyXor]

Thanks and done 👍
@come-nc Can you tell me if I should mention someone else for a review and a merge ?

@GreyXor Can you have a look at https://github.com/nextcloud/server/pull/48800/checks?check_run_id=35620554716 and see if you can fix DCO? The idea is to use git commit --signoff (or -s).
In your situation you can use git rebase commant with --signoff option to edit existing commit before force push.
You can also rebase on master to avoid the merge commits.
