Php Paypal api，获取业务\u错误

我使用带有沙盒模式的paypal php sdk。我在创建发票的每个请求上都有错误，在它正常工作之前

我从贝宝那里得到这个错误

code: 500

{  
   "name":"BUSINESS_ERROR",
   "message":"Internal error.",
   "debug_id":"71e1394c58958"
}

我找不到此错误的描述

更新

php代码

  try {
        $payPalInvoice = new Invoice();
        $payPalInvoice
            ->setMerchantInfo($this->merchantInfo)
            ->setBillingInfo([
                new BillingInfo(
                    ['email' => $invoice->getPaymentOptions()['email']]
                )
            ]);
        $payPalInvoice->setItems([
            new InvoiceItem(
                [
                    'name' => 'Order #' . $invoice->getOrder()->getId(),
                    'quantity' => 1,
                    'unit_price' => [
                        'currency' => 'USD',
                        'value' => $invoice->getOrder()->getAmountFormatted()
                    ]
                ]
            )
        ]);
        $payPalInvoice->create($this->apiContext);
        $payPalInvoice->send($this->apiContext);
        $invoice->setForeignId($payPalInvoice->getId());
        $invoice->setStateMessage($payPalInvoice->getStatus());
    } catch (\PayPal\Exception\PayPalConnectionException $e) {
        $invoice->setNextState('failed');
        $error = 'code: ' . $e->getCode() . 'data: ' . json_encode($e->getData()); // Prints the detailed error message
        $invoice->setError($error);
    } catch (\Exception $e) {
        $invoice->setNextState('failed');
        $invoice->setError($e->getMessage());
    }

我捕获\PayPal\Exception\PayPalConnectionException错误

这是PayPal错误。现在可以了。

在paypal的沙箱模式下尝试您的代码
