Lambda上的Google Actions智能家居无法正常工作

Question

我一直在尝试让我的Google Actions智能家居（nodejs）在AWS lambda中运行。 但是，它不起作用。 每当我在Google Home应用程序上连接它时，我只会收到一条消息“无法更新设置...”。 我已经正确配置了API网关，并将处理程序设置为“ index.smarthome”，如下面的图片链接所示。 为什么它不起作用，如何使我的lambda google action智能家居正常工作？

不过，我的Firebase版本正在运行（从https://codelabs.developers.google.com/codelabs/smarthome-washer/#2的洗衣机示例进行了修改）。

const functions = require('firebase-functions');
const {smarthome} = require('actions-on-google');

const app = smarthome();

exports.smarthome = functions.https.onRequest(app);

这是我在AWS lambda函数中使用的代码。 我引用了https://github.com/actions-on-google/actions-on-google-nodejs并使用无服务器创建dialogflow v2项目以使其与 lambda兼容。 lambda版本和firebase版本之间的主要区别是“ exports.smarthome”代码。

Answer 1

检查您的AWS CloudWatch日志，查看调用lambda时会发生什么。 您可以在lambda中打印到stdout并将其显示在这些日志中。

Answer 2

除了Cloudwatch日志外，您还可以查看Stackdriver日志。
