我在测试自己在Google和移动设备上的操作技能时遇到问题。它与dialogflow一起正常工作，但是当我到达由Google助手或在动作Google网页上对其进行测试时，由功能questions_ready定义的意图时，出现错误“必须设置'final_response'”。但是它可以在Dialogflow上工作，所以我不知道它在哪里。我在这里留下了我的代码，希望你们中的一些可以帮助我！谢谢！

我在Google的“操作”中获得的消息是：
-在模拟器上显示： Prueba应用程序当前没有响应。请稍后重试。
-错误： 格式错误的响应 必须设置“ final_response”。
-调试：

这里有我的Questions_Ready Intent和Dialogflow建立的Dialog上的图像，它们都可以正常运行。问题是，当我尝试测试有关“ Google动作”的技能
答案 0 :(得分：0)
在Debug json上：
debugInfo.agentToAssistantDebug.agentToAssistantJson：“由于语音响应为空，无法将Dialogflow响应解析为AppResponse”
我们可以看到Dialogflow没有返回Google的操作可以理解的任何响应。 Example response for AoG
因此，我的想法是，webhook不会为Google上的操作返回正确的格式，这与Dialogflow不同。
这里有一个存储库，用于存储Google对“操作”的响应示例：https://github.com/dialogflow/fulfillment-webhook-json/tree/master/responses/v2/ActionsOnGoogle/RichResponses
很抱歉，我无法进一步处理node.js代码，我以另一种语言实现了webhooks，但是json响应对于所有这些人都是相同的。
答案 1 :(得分：0)
