 `if ( $elements['page'] > count( $elements['pages'] ) )` in file `wp-
 includes/post-template.php` (currently on line 319) throws the following
 error when those array items are null:

 `Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of
 type Countable|array, null given in /wp-includes/post-template.php:319`

 A case where they would be null is a search request with no results where
 a plugin like Timber is used to assign $post a non-WordPress-core value.
 Adding the condition `if ( ! is_null( $elements['page'] ) && ! is_null(
 $elements['pages'] ) )` solves the problem.
