Error when using calendar from external library

I am trying to use this calendar for my vue app https://litepicker.com/#usage

In my component

<input type="text" id="litepicker">

import Litepicker from 'litepicker';
new Litepicker({ 
    element: document.getElementById('litepicker') 
  });

I also tried it in setup() with a ref instead of grabbing element by id. With both tries I am getting this error:

Is this calendar not suitable for vue, or I am just doing something wrong?
