@danil.rivero can you point me to any functional repo you have available to test this change?

I can test the merge request with mairon simulation by pushing some changes and creating 2 runners and check if they pass the pipeline.

Will test in this branch: https://git.code.tecnalia.com/tecnalia_robotics/mairon/mairon_sim/-/tree/tmp/test-ci-template?ref_type=heads

And trying to force the errors to happen in this other branch: https://git.code.tecnalia.com/tecnalia_robotics/mairon/mairon_sim/-/tree/tmp/force-ci-errors?ref_type=heads
