captionSelector: + figcaption, error when missing (null)

Hi,

first of all i want to thank you for the great lightbox script!

I use the plain JS (not the plugin) inside a WordPress site. Here I have a gallery with many images that link to their media files.

Up to here everything works wonderfully. Now I want to use the caption and select it with

captionSelector: '+ figcaption',
captionType: 'text'

This also works great, BUT only if all elements have a caption. In my case there are only some and simplelightbox hangs on them.

TypeError: Cannot read properties of null (reading 'matches')

Is there a way to prevent this?

Many thanks and best regards

Patrick
