非常感谢您的帮助

您的问题不是您未处理的函数出错，而是没有调用它

你有没有在Alexa方面包含未经处理的意图？如果是这样，您将如何尝试捕获未知值以映射到此目的？尝试这样做存在已知问题（请参阅）

在您提供的输出中，调用的意图是coffeeSummary，但coffeeName插槽的值为“蝙蝠侠”。我猜你的咖啡不知道怎么处理。作为最低要求，您应该在Lambda中的其他意图中添加错误捕获，以便它们能够优雅地处理意外值。

感谢您回答我的问题。我的第一件事是我不太确定如何添加未处理的意图。我尝试添加一个，就像我添加其他意图一样，但似乎不起作用。在我开始对此进行研究之前，我不知道我需要捕捉未知值，所以我仍在努力找出答案。@Orycle如我在回答中所述，在尝试实现未经处理的意图时存在已知问题。通常情况下，不管是否存在未处理的意图，乱七八糟的值都会映射到您的一个有效意图。您最好设计所有意图来处理错误输入、丢失/空插槽等。感谢您回复我，我将继续尝试在我的lambda意图中实现错误处理。

        console.log("UNHANDLED");
        var reprompt = "I'm sorry I didn't understand that, say help for assistance or try another coffee";
