Hello!

I created a new repository to test if my changes in that pull request work by creating a new release at my fork. It works! 😍🎉

I created this issue which was labeled:

• Testing new labeling issue 5 renanfranca/test-issue-label-github-action#7
  

Here is the github action without the warning:

• https://github.com/renanfranca/test-issue-label-github-action/actions/runs/7726031623
  

Here is the release generated at my fork using the same branch used to create this pull request:

• https://github.com/renanfranca/issue-labeler/releases
  

I am planning to use this github action at the JHipster Lite project to fix that issue:

• Consider using another github action for labelling issues jhipster/jhipster-lite#8528
