I was trying using schedule feature from @syncfusion/ej2-angular-schedule npm library. I followed the steps mentioned in the official site (https://ej2.syncfusion.com/angular/documentation/schedule/getting-started/). After successfully downloading all the dependencies, when I compiled my angular app, the Ivy compiler started throwing many errors for the existing node modules (got updated after adding syncfusion library). Although, my angular source code got compiled successfully. When I ran my app, it started throwing another error in console "Maximum call stack size exceeded".
UPDATE
I created a fresh project from latest Angular cli (Angular CLI: 10.0.8) and followed the steps mentioned in the document. Now, my new latest angular project has only code related to get the schedule view rendered. Still I am receiving "Maximum call stack size exceeded error". I guess the library is not stable for Angular.
