I am using ngx-sortable library and it's my first contact with it. According to documentation I've included the line below to have MultiDrag.
Sortable.mount(new MultiDrag(), new Swap());
Component works fine. But when I try to run my unit tests it fails with an error:
TypeError: sortablejs_1.MultiDrag is not a constructor
SortablejsModule was imported in the spec file. I spent some time on searching the internet but I couldn't find the solution. Do you know what is the reason of that error? Thank you in advance
