If you use wordpress child theme for add scripts to your theme, you should change the get_template_directory_uri function to get_stylesheet_directory_uri, for example :

Parent Theme :

add_action( 'wp_enqueue_scripts', 'add_my_script' );
function add_my_script() {
    wp_register_script(
        'parent-theme-script', 
        get_template_directory_uri() . '/js/your-script.js', 
        array('jquery') 
    );

    wp_enqueue_script('parent-theme-script');
}

Child Theme :

add_action( 'wp_enqueue_scripts', 'add_my_script' );
function add_my_script() {
    wp_register_script(
       'child-theme-script', 
       get_stylesheet_directory_uri() . '/js/your-script.js', 
       array('jquery') 
    );

    wp_enqueue_script('child-theme-script');
}

get_template_directory_uri : /your-site/wp-content/themes/parent-theme

get_stylesheet_directory_uri : /your-site/wp-content/themes/child-theme
