TOPIC: Argument #2 ($haystack) must be of type array,null

Argument #2 ($haystack) must be of type array,null 1 year 7 months ago #10978

Hi!

I get the following error when I enable PHP 8 or later, if I set it to PHP 7.4 everything works.
I understand it's a problem with PHP, but what do I have to do? Is it the hosting company I should bring it up to?

An error has occurred.
0 in_array(): Argument #2 ($haystack) must be of type array, null given

Joomla 4.2.2
PHP Version 8.1.10
