Redirect Author Archive to Custom Post Type With Query Vars?

by

With some experimentation got this to successfully redirect the archive page to the bio page:

add_filter('request', function( array $query_vars ) {

    if ( isset( $query_vars['author_name'] ) ) {
        $bio = $query_vars['author_name'];

        $query_vars = array( 'pagename' => "$bio" );
    }

    return $query_vars;
} );
