Alexa技能工具包回退意图不调用

Question

我正在使用Alexa Skills Kit开发Alexa技能，当用户说一个无效的话语时，它会回复“请求的技能的响应有问题”。

我尝试过使用AMAZON.Fallback意图，但是查看测试窗口中的json输出显示它还没有被触发。

我的后端是Lambda中的python2.7，我使用的是locale en-gb (我尝试将交互模型复制到en-us中，但得到了相同的结果)。

回退意图是用来处理无效话语的正确方法吗，还是有其他方法可以达到类似的结果？

下面是Json输入：

如果你使用的是英语或德语的技能，你应该使用回退意图。其他语言环境还不支持它。对于en-GB或en-US，您需要确保在您的语音交互模型(前端)中定义了AMAZON.FallbackIntent，并且您在后端(例如lambda)中有一个处理程序来捕获名为AMAZON.FallbackIntent的意图请求这听起来肯定是后端处理回退意图的问题(您可能没有正确捕获它)
