We recently downloaded Calendar as component with ES6 modules.
In the AppModule we imported MbscCalendarModule.
Adding the Calendar to the AppComponent results in this error when opening the frontend (built with AOT):
Cannot read property ‘extend’ of undefined (in core.js near line 72)
Frontend will not load after this JS error.
No error on ng build itself. No error in frontend if we serve frontend (without AOT).
Thanks for your help.
