I’m fairly new here, but can say that bumping your post is probably not the best way to get an answer. Just wait, if someone is able to help, they will.

Do you have the Post_Object Return Format set to return the PostID or the Post Object?
Right after your get_field, try printing out the $post_objects array and see if there is data in the returned array, and please provide the results that are displayed on the page.
