 @marv2 Welcome to WordPress Core Trac, and thanks for the ticket!

 This can happen when using the `wp_list_pluck` function which, in the
 underlying `WP_List_Util` class expects the list to be an array.

 I think adding some checks before iterating over the array in
 `WP_List_Util->pluck` to ensure the list is an actual array would be nice
 to get rid of this warning.  Perhaps throwing a `doing_it_wrong` is also

 Also, going to tag this for `needs-unit-tests`.  It would be good to have
 some "unhpappy path" tests to check some invalid types sent to the `pluck`
