I am using the fullcalendar v4 and at the moment I'm trying to open a modal on select event. After selecting a period of time from my calendar, I'm calling a function that changes the state for 'isOpen' prop of the modal, but the modal doesnt'show. Also my calendar is getting an error after calling that function. I'm getting an error which says that my calendar is not defined. I'm mentioning that I'm using react enter image description here
Okay, so the problem was that I was using the version 4.4.0 for daygrid, interaction & timegrid. If you want to open a modal using the select function from fullcalendar, I recommend you to use version 4.2.0.
