what’s the problem?

ERROR TypeError: Cannot read property ‘getApi’ of undefined

this.fullcalendar.getApi().refetchEvents();

Im not sure that i fully understood your approach. But id reccomend you to call this method inside ngAfterViewInit. You can reach this api only after your component finishes rendering calendar

ngAfterViewInit(): void { this.calendarApi = this.calendarComponent.getApi(); }

[rjs123431]

try to enclose it inside settimeout

getCalendarApi() {
        setTimeout(() => {
            this.calendarApi = this.monthFullCalendar.getApi();
        });
    }
