I am using fullcalendar 4.0, and trying to get event source record with both the methods and 10411 is the "id" filed valuse in event as:
{id : 10411,title : 'sample',start : 'date'}
var eventdetails = calendar.getEventSourceById('10411');
var eventdetails = calendar.getEventSourceById('clientEvents','10411');
Please share any ideas.
