Drupal\Core\Entity\Query\QueryException: Entity queries must explicitly set whether the query should be access checked or not

To make clearer what the issue is: Before, the code creating a query object was not required to call accessCheck(); the query object behaved as if accessCheck(FALSE) was called. Now, the code that creates a query object must call accessCheck() for that object, even without arguments, in which case it is equivalent to calling accessCheck(FALSE).

Thanks @apaderno... patch attached, works for me on 10.1.

The code has been changed as described in the issue summary, and that is the correct way to fix the issue.

Patch applied and issue fixed
Thanks @apaderno
