React : date[("get" + method)] is not a function

I'm new to Node/Webpack/React. When I switch between month/week/day view, the app often crashes and I get this error in the console: index.js?07ad:209 Uncaught TypeError: date[("get" + method)] is not a function.

please help me thanks

Code

          <MyCalendar
                popup
                selectable
                localizer={localizer}
                defaultView={[MyCalendar.Views.WEEK ]}
                components={{toolbar: CustomToolbar}}
                views={['week']}
                style={{height: 600}}
                events={this.props.events}
                eventPropGetter={(this.eventStyleGetter)}
                onSelectEvent={(slotInfo) => this.onSelectEventHandler(slotInfo)}
                onSelectSlot={(slotInfo) => this.onSelectEventSlotHandler(slotInfo)}
            />

Function

function createAccessor(method) {
  return function (date, val) {
    if (val === undefined) return date['get' + method]();
    date = new Date(date);
    date['set' + method](val);
    return date;
  };
}

this happens when the date you are trying to display is "String" when actually "date" is an "Object" type, then you could do something like this:

var DATEString = "2020-08-31T05:00:00.000Z"
var dateLike = new Date(DATEString)

example my code:

ReqCitas.data.forEach(cita => {
      Object.assign(cita,{ "uuid": uuidv4()})
      cita.start =  new Date(cita.start)
      cita.end =  new Date(cita.end)
});
