python - Alexa Skills Kit“技能执行返回 requestId 异常”错误

Question

我对 Alexa Skills Kit 非常陌生。我一直在尝试在https://www.pythonanywhere.com的网络托管服务器上制作简单的音乐播放器技能。当我尝试提出请求时

“SKILL_ENDPOINT_ERROR”

在设备日志中捕获，并具有以下描述：

“技能执行返回了 requestId amzn1.echo-api.request.e08ec414-0a30-4e95-87bb-28f315c8d4eb 的异常”。

这是我的技能请求处理程序代码：

我首先假设问题是我没有异常处理程序，但是自从我实现了一个异常处理程序后，结果没有任何变化。

有没有人解决了这个问题或知道我的代码缺少什么？
