Question

我试图将我的应用程序与Dialogflow集成在一起，并将请求发送到Mulesoft，然后从那里以Webhook指南中提到的格式发送响应。

下面是诊断信息中显示的API请求和响应：-

履行请求：-

        }
      ]
    }
  },
  {

      "simpleResponses": [
        {

 },

履行响应：-

  "richResponse": {
    "items": [
      {
        "simpleResponse": {
          "textToSpeech": "this is a simple response from Mulesoft"
        }
      }
    ]
  }
  },
  "facebook": {

  }
}
 ],
"followupEventInput": {
"name": "event name",
"languageCode": "en-US",
"parameters": {
  "param": "param value"
  }
 }
 }

在原始API响应下：-

"webhookStatus": {
"code": 3,
"message": "Webhook call failed. Error: Webhook response was empty."
}

实现状态：-

Webhook call failed. Error: Webhook response was empty.

我浏览了多篇文章，并验证了JSOn响应也是正确的。还尝试删除现有项目并创建一个新项目。

在Google操作中对此进行测试时，由于该错误，它也在下面显示了以下错误：-

  MalformedResponse
  'final_response' must be set.

有什么办法可以解决此错误。

正在Mulesoft端执行操作并发送响应，只是它无法在textToSpeech部分下显示对Google操作/对话框的响应。

Answer 1

问题似乎出在followUpEventInput / outputContexts上，将它们删除为可选的，或者正确地填充它们。

WebHook Response Format

Dialogflow V2始终会出现此错误：-Webhook调用失败。错误：Webhook响应为空
