Gitlab Runner not executing script contents

Hi there,
I have already posted this question on GitHub but maybe I can get some help here.

The question is here: Stack Overflow

The gist, is I that I have a gitlab runner which seems to be kicked off correctly on a git update.
I can see that the before_script contents runs as well things like the artifacts: section.
But the script: contents isn’t running at all, I have no idea why and I also don’t know how to debug this.

Any suggestions are greatly appreciated!

Thanks,
Greg
