Error logs in console

Hi, I'm using Literal to make a fullcalendar.
When I run it at my chorm (file:///D:/K2Five/Pramool/fullcalendar-6.1.9/examples/month-view-k2.html) It works.

But when I put the script in the Data Label and select Literal, nothing happened. The screen is white.

I have verified that the src path is correct. I have placed the library in server (C:\Program Files\K2\K2 smartforms Runtime\Styles\Themes)

download fullcalendar → https://fullcalendar.io/docs/initialize-globals

1. create DataLabel and Add Expression Script

2.This is the code in the Datalabel

<script src='/Runtime/Styles/Themes/fullcalendar-6.1.9/dist/index.global.js'></script>
<script>
  document.addEventListener('DOMContentLoaded', function() {
    var calendarEl = document.getElementById('calendar');

    var calendar = new FullCalendar.Calendar(calendarEl, {
      initialDate: '2023-01-12',
      editable: true,
      selectable: true,
      businessHours: true,
      dayMaxEvents: true,
      locale: 'th',
      events: [
        {
          title: 'All Day Event',
          start: '2023-01-01'
        }
      ]
    });

    calendar.render();
  });

</script>
<style>

  body {
    margin: 40px 10px;
    padding: 0;
    font-family: Arial, Helvetica Neue, Helvetica, sans-serif;
    font-size: 14px;
  }

  #calendar {
    max-width: 1100px;
    margin: 0 auto;
  }

</style>
<div id='calendar'></div>

The screen is white. and no error

I want to see JavaScript errors.
