fullcalendar4.2.0 datesRender error (only ie)

Question

I am customizing fullcalendar4.2.0. I get a "datesRender error" only in IE (v.11), but Firefox and Chrome operated well.

Help me!

    datesRender: function(info) {//일 삭제   viewSkeletonRender
        if(info.view.type == 'dayGridMonth') {
            info.el.querySelectorAll('.fc-day-number').forEach(function(v,i,a) {
                a[i].innerText = v.innerText.replace(/일/, '');
            });
        } else if(info.view.type == 'timeGridWeek') {
            info.el.querySelectorAll('th.fc-day-header a').forEach(function(v,i,a) {
                var s = v.innerText.trim().split('.');
                a[i].innerHTML = '<small>'+s[2]+'<\/small>'+s[1];
            });
        }
    }

Error message in IE:

exception in window.onload:Error:An error has accourredJSPlugin,3005
