Dialogflow v2 错误“必须设置 MalformedResponse 'final_response'”

Question

只有在使用 simulator/google 助手时才会出现此错误。当我在 DialogFlow 中使用 Slack 集成或测试时，它工作得很好。

我检查了这个 about settings in DialogFlow, but that wasn't my issue. I checked this question 但因为我在我的 webhook 中使用了 python，所以我不确定这是否会为我解决问题，或者没有。

我正在做以下事情：

首先，用户调用我的任何一个意图，这些意图通过 Webhook 连接到我的 python 代码。调用此 intent1.

其次，我检查代码中 intent1 的响应 (response1)。

第三，我通过后续事件 event2.

将 response1 发送到另一个意图 intent2

我之所以这样做只是为了兴趣，是因为我允许多种类型的对话流。第一个是常见问题解答，第二个是定向对话。

我发回的 JSON 是：

"followupEventInput":{  
              "name":"EventName",
              "parameters":{
                  "speech": str(speech)
                  }
              }

EventName 是 event2.

speech 是 response1

我也试过将它添加到 JSON，但它没有改变任何东西：

,"payload": {"google":{"expectUserResponse": False}}

模拟器的调试显示：

Answer 1

agentToAssistantJson 字段的值包含消息 "Failed to parse Dialogflow response into AppResponse because of empty speech response"。正如它所暗示的，无论您在回复中发送什么，都缺少语音信息。

您没有具体说明 Event2 在做什么、它发回了什么或者它对参数做了什么（如果有的话），但可能的问题是它没有发回任何东西。仅将语音作为参数包含在内没有任何作用 - 参数只是信息，而不是回复。

虽然后续事件有一些用途，但大多数时候它们并不是您真正想要的。如果您想回复来自 fulfillment 的消息 - 只需回复消息即可。
