The function in question can be found in wp-admin/includes/ajax-actions.php file. update_post_parent_caches Expects an array on post objects. So pass the array posts into the function after line 3014.

There are a lot of caching related changes in 6.1 and a dev note should be written collecting them all. Marking this for inclusion.
