将自定义帖子类型分类法显示为存档页面

Question

Hello I have a custom post type called results . I also created categories for that specific post type using a taxonomy. I'm not sure if I set it up correctly, but the code I have works so I'm sticking with it. If you see a better way or any errors please let me know.

I am able to create a custom post and set a category to it. Next I would like to create a categories page that will act like the regular archive.php but just for the category of the custom post types.

So say I have a custom post for results and I have its category set to car accidents I would like a way to display them all just like archive.php does for normal posts.

I tried going to a url like this but I get sent to a 404 page, even though I have an archive-results.php

www.myurl.com/results/categories/car-accidents

Here is the code I used to set up the custom post type and the taxonomy. Sorry If its long but I feel like its necessary to include everything.

// Create custom post type
function create_posttype() {
    register_post_type( 'Results',
        array(
            'labels' => array(
                'name' => __( 'Results' ),
                'singular_name' => __( 'Results' )
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'results'),
            'taxonomies'  => array( 'results', 'result-category' ),
        )
    );
}
add_action( 'init', 'create_posttype' );

//Create category for specific post type
function tr_create_my_taxonomy() {
    register_taxonomy(
        'results-categories',
        'results',
        array(
            'label' => __( 'Result Categories' ),
            'rewrite' => array( 'slug' => 'result-category' ),
            'hierarchical' => true,
            'has_archive' => true
        )
    );
}
add_action( 'init', 'tr_create_my_taxonomy' );

Am I missing something that is preventing this url from working?

www.myurl.com/results/categories/car-accidents

Thanks in advance

function namespace_add_custom_types( $query ) {
if( is_category() || is_tag() && empty( $query->query_vars['suppress_filters'] ) ) {
$query->set( 'post_type', array(
 'post', 'nav_menu_item', 'cmc-description'
    ));
  return $query;
}
}
add_filter( 'pre_get_posts', 'namespace_add_custom_types' );
