代码检查帮助：Lambda函数调用Amazon Connect API进行出站呼叫

Posted 2021-04-19

（我是初学者 - 在这里寻找大师们的一些指导/指导）

我正在尝试写一个Lambda来拨打电话号码并启动一个简单的Connect呼叫流程。这是我正在尝试的代码和我得到的错误。有什么建议？

Sample Lambda Code for calling Connect API

我正在使用为出站呼叫配置的默认出站呼叫流（AWS内置呼叫流）

这是我在进行独立Lambda测试时遇到的错误

答案

你的错误（ContactNotFoundException）来自connect.stopContact电话

如果你检查connect:StopContact你可以看到当你指定的ContactNotFoundException找不到时会发生contactId。这意味着：

• 你有错误的params2.ContactId（即你试图阻止一个不存在的联系人）。
• 你有错误的params2.InstanceId，这意味着即使你有正确的联系人ID，它们在这个实例上也不存在。

我怀疑你有contactId错了。如果我们看看connect:StartOutboundVoiceContact，你会看到它返回ContactId的值。我怀疑你应该捕获这个值，然后在你的params2对象中使用它，而不是硬编码的值。
