尝试在 Dialogflow 有效负载中显示来自 Firestore 数据库的数据时出现“未处理的拒绝”消息

Question

我是这方面的新手，我已经阅读了许多类似的文章，但没有一篇对我有用。 我真的需要密切的帮助。 我正在使用 Dialogflow 和使用 Fulfillment Inline Editor 开发一个聊天机器人。 我想要一个意图，当用户输入“Read db”时，将触发 readDB() function，并且来自数据库的数据将存储在自定义有效负载中。 这是我的代码：

'use strict';
 
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const {Payload} = require("dialogflow-fulfillment");

const serviceAccount = {

  "project_id": "repro-ljcq",
  "private_key_id": "b5f2d8d10dd6482f450929469ef05859e426c4c3",

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });
    
  function displayDB(){
    return admin.firestore().collection('ICR').doc(sessionID).get()
      .then(doc => {
      data = doc.data();
      const payload = {
          "accordion": {
            "title": "Individual Client Record",

        };
        agent.add(new Payload(agent.UNSPECIFIED, payload, {rawPayload: true, sendAsMessage: true}));
    });
  }

  let intentMap = new Map();
  intentMap.set('ReadDB', displayDB);
  agent.handleRequest(intentMap);
});

这就是我的数据库结构的样子。

Firestore 数据库结构

在我的客户端应用程序中，当我使用虚拟值时它可以正常工作。 这就是它应该的样子。

前端的聊天机器人响应

我可以查看日志中的数据，但每当我尝试将其放入有效负载时都会收到“未处理的拒绝”错误消息。 这是日志：

我不知道这是由于错误执行有效负载还是因为超时（从 firebase 检索数据需要超过 5 秒才能达到 Dialogflow 超时）

Google Cloud Console Dialogflow 5 秒响应时间

我真的需要帮助：/
