贝宝沙盒返回内部服务错误

Question

我正在尝试使用 PayPal 沙盒测试自动信用卡处理，但遇到了问题。当我收取 105 美元 的费用时，我会得到一个 INTERNAL_SERVICE_ERROR，其调试 ID 为 de753957a889d。例如，如果我返回并将金额更改为 $115 之类的其他金额，则费用会按预期进行。我尝试了几种不同的金额，而 $105 似乎是唯一给我错误的金额。

以下是日志文件中的行：

您是否有任何机会在您的沙盒帐户上启用了“负面测试”？
https://developer.paypal.com / > 应用程序 > 沙盒帐户 > 查找您的帐户 > 点击“个人资料”> 设置。

负测试允许您通过将特定错误代码作为“AMT”值传递来测试我们经典 API 的特定错误条件。
例如，对于 API 错误代码 12345，您可以设置 AMT=123.45。
对于您的错误情况，我看到我们在内部返回 API 错误代码 10500。这让我强烈怀疑您为您的一个沙盒帐户打开了“负面测试”。

如果您多次使用相同的卡详细信息，则可能会遇到此问题。 请使用其他卡，您不会遇到此类问题。
