After upgrading to PHP 8.1, the Yoast plugin is occasionally throwing an Uncaught TypeError on the edit post (wp-admin/post.php) page. See below:
An error of type E_ERROR was caused in line 1027 of the file /srv/htdocs/wp-content/plugins/wordpress-seo/inc/class-wpseo-meta.php. Error message: Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, bool given in /srv/htdocs/wp-content/plugins/wordpress-seo/inc/class-wpseo-meta.php:1027

thrownIs this due to PHP 8.1.x being less forgiving of type mismatches ? I was on PHP 8.0.x for a while with no such issues, but this came up within 24 hours of upgrading to 8.1, so am assuming it’s a change in behaviour relating to 8.1 ?
