javascript - Dialogflow：如何在环聊中接收图片？(Javascript)

Question

我正在尝试在连接到环聊的 Dialogflow 中构建一个聊天机器人。我正在接收图像等文件。

我发现了一个关于“如何在 WhatsApp 聊天机器人（通过对话流）上接收图像、音频、视频和富媒体”的youtube 视频。我已按照说明进行操作，但有些东西不起作用。

这是我的 index.js 代码（内联编辑器 - Fulfillment）：

'use strict';

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

process.env.DEBUG = 'dialogflow:debug';

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });
  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

function welcome(agent) {
    agent.add(`¡Bienvenido a mi chatbot! ¿Quieres subir un código QR?`);
  }

  function fallback(agent) {
    agent.add(`Lo siento, no te he entendido.`);
    agent.add(`¿Podrías repetir otra vez?`);
  }

function mediaHandler(agent) {
 exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
 let originalRequest = request.body.originalDetectIntentRequest; 
 agent.add(`Aquí tengo el archivo que me has mandado, gracias.` +  originalRequest.payload.data.MediaUrl0);
  });
  }

let intentMap = new Map();
  intentMap.set('Default Welcome Intent', welcome);
  intentMap.set('Default Fallback Intent', fallback);
  intentMap.set('Hangouts Media - fallback', mediaHandler);

  agent.handleRequest(intentMap);});

这些是我的意图：

意图

这是错误：

错误：Exports.dialogflowFirebaseFulfillment.functions.https.onRequest (/srv/index.js) 处的 WebhookClient.handleRequest (/srv/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:327:29) 中没有请求意图的处理程序:94:9) 在 cloudFunction (/srv/node_modules/firebase-functions/lib/providers/https.js:26:47) 在 /worker/worker.js:783:7 在 /worker/worker.js:766: 11 在 _combinedTickCallback (internal/process/next_tick.js:132:7) 在 process._tickDomainCallback (internal/process/next_tick.js:219:9)

最后，这是 package.json：

{
  "name": "dialogflowFirebaseFulfillment",
  "description": "This is the default fulfillment for a Dialogflow agents using Cloud Functions for Firebase",
  "version": "0.0.1",
  "private": true,

    "qrcode-decoder": "^0.1.2",
    "xmlhttprequest": "^1.8.0",

  }
}

你知道我该如何解决我的错误吗？先感谢您！
