the_post_navigation() for current term only

Hi,

I have custom post types “project” and custom taxonomy – castingcategory.
There is also terms like – movies, music …

I want when I’m on single-project.php post navigation to navigate true posts from current term only. Let say movies.
When I reach last post from “movies” avalible navigation to be previews only. Now there is “Next” link wich is pointing to other term – music.

I tried code like this but something there I do wrong:

the_post_navigation( array(
				'next_text' =>
					'<span class="meta-nav" aria-hidden="true">' . __( 'Next', 'casting' ) . '</span> ',
				'prev_text' =>
					'<span class="meta-nav" aria-hidden="true">' . __( 'Previous', 'casting' ) . '</span> ',
				'in_same_term' => true,
				'excluded_terms'     => '',
				'taxonomy' => 'castcategory',
			) );

Help me, please.
