WordPress ACF Order by

I am trying to order posts on my category page from newest to oldest and then from A to Z using an Advanced Custom Fields variable “inductee_last_name”.

Here’s my WP_Query:

$currentCategory = single_cat_title("", false);

	$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
	$query_args = array(
	  'category_name' => $currentCategory,
	  'posts_per_page' => 30,
	  'orderby'   => 'meta_value',
	  'meta_key'  => 'inductee_last_name',
	  'order' => 'DESC',
	  'paged' => $paged
	);

	$the_query = new WP_Query( $query_args );

If I remove orderby and meta_key, my query works just fine. But as soon as they’re added in. It doesn’t pull anything up.

Any help would be greatly appreciated.

Thank you.
