Additional info

in calendar/src/components/Editor/FreeBusy/RoomAvailabilityModal.vue:

Theres a fullcalendar view initiated with options()

These options generate two errors:

1.  		selectable: true,
    		select: this.handleSelect,
   

But this.handleSelect is not defined in methods(). So this is undefined (that's why handler.apply is crashing)

Adding in methods
handleSelect() {
console.log('handleSelect')
}

Solves the crash, but doesn't select the schedule time ;)

2. option: dateClick: this.findFreeSlots(),

The trigger won't be able to handler.apply on the return from this function, wich is a promise.

You should either use:
dateClick: () => this.findFreeSlots(),
Or (without parenthesis)
dateClick: this.findFreeSlots,

But when doing this, nothing really happens.
