paypal - DoExpressCheckout 10004 - 没有额外的错误信息

Question

我们的 PayPal Express Checkout 集成有问题。我们看到从 DoExpressCheckout 返回的错误代码 10004 说“交易因参数无效而被拒绝。有关详细信息，请参阅其他错误消息。”但响应不包含其他错误消息。

这在我们的整合中是随机发生的。它大约在一个月前开始，已经发生了 70 次，而成功的交易有 1430 次。

它看起来是随机的。与任何特定金额、浏览器类型、交易时间等无关。一个用户可能会遇到几次失败，然后使用相同的 token 重试并让它通过。一些用户在 10 分钟后回来或更改浏览器并且它有效。大多数放弃。

如果有任何建议，我将不胜感激，有没有办法针对此错误检索更多调试信息？
