Fatal error: Uncaught TypeError: array_map() bug :: php 8.2

Issue

I have recently enabled your plugin as well as publishpress revisions pro while using elementor and acf fields. When I try and save a revision on a page built with elementor I was receiving the following error ::

Fatal error: Uncaught TypeError: array_map(): Argument #2 ($array)?must be of type array, string given in?/var/www/html/wp-content/plugins/relevanssi/lib/common.php:1374

That line is part of the relevanssi_filter_custom_fields function. The issue does not occur if I am not creating a revision.

The site is running on php 8.2

Work Around ::

I was able to work around the issue by setting the Custom fields indexing option to visible within the Relevanssi settings admin.

Seems like a bit of an edge case but I figured I would drop you a note about it.

Here is the stack trace ::
