Have you already contact our help centre?

• Yes, I have contact the help centre.

Describe the problem

This is not as much of a problem for the OVH team, because from what I can see, you mostly develop in this repository. However, it is a small problem for outside contributors. Basically, if you have forked the repository, some actions will fail by default, like auto-label-merge-conflicts, as the labels are not forked from the original repository. So it just throws an error. This is the only one I have currently had issues with.

Describe the solution

This should be fixable by adding the following for example:

triage:
    if: github.event.repository.fork == false

I don't really want to open a pull request for this, as I don't know how you approach this and I don't want to break any builds. But it should work.
