I can confirm I am experiencing the same issue and can see that you are passing an array into the apply_filters() method when the doc block shows that it expects a string.

/wp-includes/plugin.php

* @since 0.71
 *
 * @global WP_Hook[] $wp_filter         Stores all of the filters and actions.
 * @global string[]  $wp_current_filter Stores the list of current filters with the current one last.
 *
 * @param string $hook_name The name of the filter hook.
 * @param mixed  $value     The value to filter.
 * @param mixed  ...$args   Additional parameters to pass to the callback functions.
 * @return mixed The filtered value after all hooked functions are applied to it.

function apply_filters( $hook_name, $value ) {
