I have blog post counts which happen when a user views a blog post via ajax and the rest api.

In the database I have a meta key and value like so:

table: wp_postmeta
post_id: blog post ID
meta_key: blog_post_count
meta_value: number ie: 1, 2, 3 etc. 

This basically stores the blog post ID and the count. On a page, I am trying to display the ID with the highest count only.

$views = new WP_Query( array(
    'orderby' => 'meta_value_num',
    'meta_key' => 'blog_post_count',
    'order' => 'DESC',
    'posts_per_page' => 1
) );

Running this in a standard wordpress loop however displays all posts and not with the highest count first so my Query is obviously not correct.
