Paypal DoExpressCheckout 10004-无其他错误消息

我们的PayPal Express结帐集成存在问题。我们看到一个错误从DoExpressCheckout返回，代码10004说“事务因无效参数而被拒绝。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

这在我们的集成中是随机发生的。它大约在一个月前开始，已经发生了70次，而成功的交易只有1430次

这似乎是随机的。不受任何特定金额、浏览器类型、交易时间等的限制。一个用户可能会出现多个故障，然后使用相同的令牌重试并通过。一些用户10分钟后回来，或者更换了浏览器，它就可以工作了。大多数人放弃了

我非常感谢您的建议，有没有办法为这个错误检索更多的调试
