WP_GET_OBJECT_TERMS order by problem

When i try to use

$args=array('orderby'=>'term_order', 'order' => 'ASC');
$product_terms = wp_get_object_terms(get_the_ID(), 'category',$args);

when using DESC / ASC it return the same results.
but when using ‘orderby’=>’term_id’ it work perfect and return the right order!!
