Technical problems when using BootstrapModal

[SilverYoCha]

Technical errors occurs when showing a modal dialog extending BootstrapModal.

To Reproduce
Extending BootstrapModal:

  const MyModalDialog = BootstrapModal.extend({
    id: "my-modal-dialog",
    initialize : function() {
      ...
    },
    ...
  });

And showing it:

  function showMyDialog(ev) {
    ev.preventDefault();
    const chatView = getChatViewFromElement(ev.currentTarget);
    const myDialogModel = new Model();
    _converse.api.modal.show(MyModalDialog, {
      'model': myDialogModel,
      'chatroomview': chatView
    }, ev);
  }

Then occurring javascript errors:

Expected behavior
The modal dialog opens without any javascript error.
