Hello @evegufy @MaximilianHauer

I noticed that the quality gate is failing due to some issues in the YAML files. The only change I made related to these files is moving their folder location, without modifying the content itself.

Could you please take a look and help me resolve the issue? It seems like the errors might be triggered by the folder restructuring.
