I want to move account to other MMC with MoveOperation. But give an error: ManagedCustomerServiceError.INVALID_DESCRIPTIVE_NAME
$managedCustomerService = $adWordsServices->get($session, ManagedCustomerService::class);
$moveOperation = new MoveOperation();
$moveOperation->setOldManagerCustomerId("XXX-XXX-XXXX");
$moveOperation->setOperator(Operator::SET);
$moveOperations = [];
$managedCustomerLink = new ManagedCustomerLink();
$managedCustomerLink->setClientCustomerId("XXX-XXX-XXXX");
$managedCustomerLink->setLinkStatus(LinkStatus::ACTIVE);
$managedCustomerLink->setManagerCustomerId("XXX-XXX-XXXX");
$managedCustomerLink->setPendingDescriptiveName("Test Account");
$moveOperation->setOperand($managedCustomerLink);
$moveOperations[] = $moveOperation;
$result = $managedCustomerService->mutate($moveOperations);
