node.js - Firebase Firestore 错误：Dialogflow 参数中的“无效使用类型‘未定义’作为 Firestore 参数”

问题描述

我有一个在 Dialogflow 中制作的聊天机器人，我正在尝试按照本教程将用户数据添加到 Firestore 。它不适用于我的参数，即使在尝试定义其他上下文或其他方式来获取参数时也是如此。

当我尝试打印完整的输出以捕获未定义的值时（如此处所述），Firebase 只会打印“未定义”。我在这里错过了什么吗？

在此处输入图像描述

我在 Dialogflow Fulfillment webhook 上的 index.js：

'use strict';

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });

  function getNameHandler(agent) {
    let email = agent.parameters.email; 

    db.collection("users").add({ name: email });

    agent.add(`Thank you, $email`);
  }

  let intentMap = new Map();
  intentMap.set('Final', getNameHandler);
  agent.handleRequest(intentMap);
});

解决方案

错误消息（阅读全文）：

错误：参数“data”的值不是有效的 Firestore 文档。不能使用“未定义”作为 Firestore 值（在字段名称中找到）。

告诉您您为名为“name”的字段传递的值未定义。鉴于这些代码行：

let email = agent.parameters.email; 
db.collection("users").add({ name: email });

断言是email未定义的。所以，你必须弄清楚为什么会这样。
