I am running into an issue with having multiple scheduler instances on a page (I have the pro version) and using drag_between with the scheduler’s destructor. In my Angular project, in ngOnDestroy I call scheduler.destructor() and when this goes into the “onDestroy” event for drag_between, it crashes after doing an .unshift() of the scheduler instances.
Unshift() returns a length, not a an element (a scheduler) of the array of schedulers. After this operation it crashes because it cannot execute on a number when it is expecting a scheduler object.
