Recently I have following problem. In grid component I want to use orderBy function to sort data in my table (like in the example). Of course everything works fine. Problem coming out when I try to run my tests (npm run test). I get the following error: "XHR error (404 Not Found) loading node_modules/@progress/kendo-data-query/dist/npm/main.js". I saw that in my *.js file compiler added "kendo-data-query" to System.register array. Is there any solution for that problem? I hope that you can understand my problem here.
