Alexa 自定义技能：获取 FallbackIntent 而不是验证提示

Question

我有一个带有GetMenuIntent 的交互模型，我可以用“what's for {meal}”调用它。 meal 是一个 MealType 自定义槽，允许值为“breakfast”和“lunch”。我在GetMenuIntent 中的meal 插槽上添加了验证，以仅允许在插槽类型中定义的那些值，并且它适用于那些配置的值。

但是，在保存并构建模型后，当我将“晚餐吃什么”放入 Utterance Profiler 或交互式测试器中时，它最终调用了我的 FallbackIntent 而不是重新提示输入正确的值。

我觉得我正在尝试做的与亚马逊自己的示例 here 并没有太大不同。

这里的“午餐吃什么”正常工作：

这里的“晚餐吃什么”忽略了我的 GetMenuIntent 并改为调用 FallbackIntent：

这是我的交互模型：

由于这是 6 个月大，我假设您现在已经知道您的交互模型只包括午餐和早餐。
