I'm using a 5.2 community version.
I have found another guy with the same problem and there is a solution: Aikau: How to call a repo webscript from an aikau widget
It works for me.
If I follow the example by Parashift blog I have this error: Could not find compressed file: /parashift/action/QuickPrint.js
I attach the folder structure of my project, can you check it? screen folder structure — imgbb.com
It looks like they left a small thing out - the definition of a custom Dojo package "parashift". That can also be part of the extension XML, i.e. I have this in one of my modules.
My extension.xml is placed in site-data/extensions/ folder.
I have moved parashift/action/QuickPrint.js under site-webscripts folder
By the last moving, log doesn't show me the previous error but in the actions of faceted-search page i show
There is not a quick print action.
The JS file was in the right place - you only needed to add a package for parashift and specify its location as "parashift" (the first-level folder below META-INF). Putting that file in site-webscripts will do nothing for you.
Good to know that "how to call a Repository web script" was your original problem. If you had given that information initially as your use case we could have helped you sooner..
