repeating destroy and init calls triggering the error Uncaught (in promise) TypeError: Cannot convert undefined or null to object

[studentIvan]

Source code:

import PhotoSwipeLightbox from 'https://unpkg.com/photoswipe/dist/photoswipe-lightbox.esm.js';

const lightbox = new PhotoSwipeLightbox({
  gallery: '#my-gallery',
  children: 'a',
  pswpModule: () => import('https://unpkg.com/photoswipe'),
});

lightbox.init();
lightbox.destroy();
lightbox.init();
lightbox.destroy();
lightbox.init();
lightbox.destroy();
lightbox.init();

(Object.keys(this._listeners)).forEach((name) => {

this._listeners is null in this case.

Playground what reproduces the bug:

Try to open any image and check the developer console

p.s.: Who faced with this problem on some dynamic data - use dataSource attribute instead of gallery and children combination. Use pswpLightbox.loadAndOpen(index) for opening the image.

The script isn't designed to be used after it's destroyed, but I can see how it can be an issue. Will try to improve docs/errors.
