Redis Object Cache – Fatal Error

Hi,

This error keeps happening in my wordpress site, not sure which one of the plugins is causing it (wpdiscuz or redis object cache)

[31-Dec-2022 15:43:38 UTC] PHP Fatal error:  Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, bool given in /wp-content/object-cache.php:1242
