How can I make entityQuery('commerce_order') return completed orders? Under Drupal Commerce 8.x-2.13 I find that the query 

Drupal::entityQuery('commerce_order') 


with no conditions attached returns ONLY incomplete orders (when called in the context of an API endpoint) - and if I apply any parameters exclusive of incomplete orders such as 

$query-&gt;condition('state', 'completed');


it returns nothing. How can entityQuery be made to retrieve data on completed orders?
The solution is apparently to add $query-&gt;accessCheck(FALSE);.
