Hi, I'm using the last version module (4.1.1) Instead of using order collection, repository is use with searchcriteria. File : /vendor/checkoutcom/magento2/Model/Service/OrderHandlerService.php ``` /** @var OrderInterface $order */ $order = $this->orderRepository->getList($search)->setPageSize(1)->getLastItem(); ``` Magento getlist load all customer orders before limiting the query with last item.
