Answer 1

You forgot to call the array.

<?php
// Primary navigation menu.
wp_nav_menu( array(
    [
        'menu_class' => 'main-nav navbar-nav ml-auto',
        'container' => false,
        'theme_location' => 'header-menu',
        //'items_wrap'      => '<ul>%3$s</ul>',
        'depth' => 4,
        //
    ]
)  );
?>
