I saw that there was a related commit Maintenance: Update to Sprockets v4 · zammad/zammad@c6e38d1 · GitHub that upgradd sprockets to version 4, claiming it not using sassc, but somehow on our system something went wrong and it tries to load sassc.

Any help is appreciated, I am currently spinning up a vm to debug this further myself.

I have found the problem, some of our addons placed *.scss files in /opt/zammad/app/assets/stylesheets/addons/, which caused this broken code path to be triggered.

As a fix for now I’ve manually converted them into css files.

Are scss files used like this unsupported?
