Malformed response error : empty speech response while making my agent

Question

我正在制作 dialogflow 应用程序，将用户链接到与用户所说的号码相关的每个链接。

我得到了 google codelab 的实现代码并对其进行了编辑。

但是当我尝试使用 Card 和其他东西创建可点击的 url 链接时，"MalformedResponse: Failed to parse Dialogflow response into AppResponse because of empty speech response" 发生了。

我为此使用 Dialogflow InlineEditor。

尝试 app.buildRichResponse 但也失败了

这是我的 node.js 代码。

'use strict';

// Import the Dialogflow module from the Actions on Google client library.
const {dialogflow} = require('actions-on-google');

// Import the firebase-functions package for deployment.
const functions = require('firebase-functions');

// Instantiate the Dialogflow client.
const app = dialogflow({debug: true});

const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

// Handle the Dialogflow intent named 'favorite color'.
// The intent collects a parameter named 'color'.
app.intent('getJobs', (conv, {number}) => {
    const jobNum = number;
    // Respond with the user's lucky number and end the conversation.
    if (number == 1) {
      conv.ask(new Card({
           title: `Title: this is a card title`,
           imageUrl: 'https://dialogflow.com/images/api_home_laptop.svg',
           text: `This is the body text of a card.  You can even use line\n  
    breaks and emoji! `,
           buttonText: 'This is a button',
           buttonUrl: 'https://docs.dialogflow.com/'
          }));

    } else if (number == 2) {
      conv.close('camera on');
    } else {
      conv.close('unknown number');
    }
});

//Set the DialogflowApp object to handle the HTTPS POST request.
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);

我认为问题是，当数字为 1 时，您只使用丰富的响应，这可能会导致 "MalformedResponse: Failed to parse Dialogflow response into AppResponse because of empty speech response" 错误，因为没有任何助手可以用语音响应。没有简单响应就不能使用富响应。

您还试图同时使用 actions-on-google 和 dialogflow-fulfillment 库。这也可能导致问题。你可以试试：

   function getJobs(agent) {
     agent.add(`This message is from Dialogflow's Cloud Functions for Firebase editor!`);
     agent.add(new Card({
         title: `Title: this is a card title`,
         imageUrl: 'https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png',
         text: `This is the body text of a card.  You can even use line\n  breaks and emoji! `,
         buttonText: 'This is a button',
         buttonUrl: 'https://assistant.google.com/'
       })
     ); 
intentMap.set('getJobs', getJobs);

或

const { dialogflow, BasicCard, Image, Button } = require('actions-on-google');
app.intent('getJobs', (conv, {number}) => {
conv.ask('This is simple response...',new BasicCard({
  text: `This is a basic card.`
  subtitle: 'This is a subtitle',
  title: 'Title: this is a title',
  buttons: new Button({
    title: 'This is a button',
    url: 'https://assistant.google.com/',
  }),
  image: new Image({
    url: 'https://example.com/image.png',
    alt: 'Image alternate text',
  }),
  display: 'CROPPED',
}));
});
