代码检查帮助：Lambda函数用于调用Amazon Connect API进行出站调用

Question

（我是一个普通的初学者-在这里寻找大师的指点/指导）

我正在尝试编写一个Lambda来拨打电话号码并启动一个简单的连接呼叫流。下面是我正在尝试的代码和我得到的错误。有什么建议吗？

调用Connect API的示例Lambda代码

我正在使用为出站调用配置的默认出站调用流（AWS内置调用流）

这是我在进行独立Lambda测试时遇到的错误

Answer 1

您的错误（ConrectNotFoundExc0019）来自connect.stop联系人调用

如果选中connect:StopContact，则当无法找到指定的联系人ID时，会出现ContactNotFoundException。这意味着：

• 你有错误的参数2。ConrectId（即您试图停止不存在的联系人）。
• 你有错误的参数2。InstanceId这意味着即使您有正确的联系人ID，他们在这个实例上也不存在。

我怀疑你的联系人ID有误。如果我们查看connect:StartOutboundVoiceContact，您将看到它返回ContactId的值。我怀疑您应该捕获这个值，然后在params2对象中使用它，而不是硬编码的值。
