试图调用方法＆＃34; getClientId＆＃34; on class＆＃34; ArrayObject＆＃34;

Question

我正在使用Payum 0.12 + Paypal Express Checkout并在完成操作时遇到此错误：

  

尝试在类“ArrayObject”中调用方法“getClientId”   DetailsController.php在线...

这是控制器代码：

<?php
namespace Custom\CustomBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Payum\Core\Registry\RegistryInterface;
use Payum\Core\Security\HttpRequestVerifierInterface;
use Payum\Core\Exception\RequestNotSupportedException;
use Payum\Core\Model\OrderInterface;
use Payum\Core\Request\GetHumanStatus;
use Payum\Core\Request\Sync;

class DetailsController extends Controller
{
  public function completeAction(Request $request) {
    $token = $this->get('payum.security.http_request_verifier')->verify($request);

    $payment = $this->get('payum')->getPayment($token->getPaymentName());

    try {
      $payment->execute(new Sync($token));
    } catch (RequestNotSupportedException $e) {}

    $payment->execute($status = new GetHumanStatus($token));

    /** @var OrderInterface $order */
    $order = $status->getModel();

    return $this->render('CustomBundle:Default:complete.html.twig', array(
      'status' => $status->getValue(),
      'order' => htmlspecialchars(json_encode(
        array(
          'client' => array(
            'id' => $order->getClientId(), //<--- Error here
            'email' => $order->getClientEmail(),
          ),
          'number' => $order->getNumber(),
          'description' => $order->getCurrencyCode(),
          'total_amount' => $order->getTotalAmount(),
          'currency_code' => $order->getCurrencyCode(),
          'currency_digits_after_decimal_point' => $order->getCurrencyDigitsAfterDecimalPoint(),
          'details' => $order->getDetails(),
        ),
        JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE
      )),
      'paymentTitle' => ucwords(str_replace(array('_', '-'), ' ', $token->getPaymentName()))
    ));
  }
}

即使我在没有Paypal Exress Checkout的情况下使用“离线”付款选项，我也会收到此错误消息。我错过了什么吗？
