如何解决Alexa 连接到 MongoDb 后无法发送技能请求
我的 Alexa 技能发生了奇怪的事情。我的技能需要连接 MongoDB 并保存数据。每当我连接到数据库时，Alexa 都会给我这样的响应：“请求的技能响应出现问题”。这完全很奇怪，因为几天前我的数据库和 Alexa 技能完美运行。现在，突然间，即使我的数据库已连接并创建文档，我也没有收到 Alexa 的任何响应。
下面是我的 JSON INPUT 和来自 Launchrequesthandler 的代码：

解决方法
如果您在 lambda 中托管技能，则可能有超时的机会。数据库操作可能需要一些时间，同时 lambda 关闭了会话。
我认为以下日志行表明相同。
**2021-07-19T16:40:08.023Z 6a416b77-5d2c-4ebe-8ac4-dec09f67e9b9 Task timed out after 8.01 seconds**
此外，我们必须考虑允许 Alexa 从端点接收响应的最长时间。最好将响应限制为 8 秒。如需更多信息：DeferredResponse
