get_post_meta not working on my custom-function page

WordPress uses a global $post to keep track of the current post the user is viewing. Whenever you call functions like the_title() or get_the_ID() it uses that global $post to pull that data. In your code snippet you’re using get_posts() which generally does not overwrite the global $post object unless you specify with setup_postdata( $post ).

The easiest thing to do is to simply modify your metadata line and use:

$custom_meta_writer = get_post_meta( $post->ID, 'writer_meta_key', true );
