尝试将成员添加到列表中，但一直收到此错误：无法验证提交的资源。有关特定字段的详细信息，请参阅'errors'数组。

以下是完整的输出-

下面是app.js文件：

const express = require("express");
const app = express();
app.use(express.static("public"));
const mailchimp = require("@mailchimp/mailchimp_marketing");
const bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({ extended: true }));
const request = require("request");
const https = require("https");
const axios = require("axios");
const { response } = require("express");
const port = 3000;
app.get("/", (req, res) => {
  res.sendFile(__dirname + "/signup.html");
  mailchimp.setConfig({
    apiKey: 'rupak:ec9e6dcf527*****8655da1b-us13',
    server: "us13"
  });
});
app.post("/", function(req, res){
    const firstName = req.body.firstName;
    const lastName = req.body.secondName;
    const email = req.body.email;
    console.log(firstName, lastName, email);
   
    const data = {
      members: [
        {
            email_address: email,

            merge_fields: {
                FNAME: firstName,
                LNAME: lastName
            }
        }
      ]
    }
    const jsonData = JSON.stringify(data);
    
    let url = 'https://us13.api.mailchimp.com/3.0/lists/20b****bce/members' ;

        })

    request.write(jsonData);
    request.end();

据我所知，email_address字段不是空的，因为我已经记录了电子邮件的输出，我可以看到我输入的电子邮件正在显示。

编辑

我尝试了另一个method，但现在我得到了这个很长的错误消息，我根本不明白
这里有一小部分

这是更新app.js文件

//jshint esversion: 6
const express = require('express');
const bodyParser = require('body-parser');
const mailchimp = require('@mailchimp/mailchimp_marketing');
const app = express();
app.use(bodyParser.urlencoded({

app.use(express.static("public"));
app.get("/", function(req, res) {
  res.sendFile(__dirname + "/signup.html");
  //setup mailchimp
  mailchimp.setConfig({

    server: "us13"
  })
});
app.post("/", function(req, res) {
  var firstName = req.body.firstName;
  var lastName = req.body.secondName;
  var email = req.body.email;
  console.log(`${firstName} ${lastName} ${email}`);
  const run = async () => {
    //testing if server is working fine
    // const response = await mailchimp.ping.get();
    // console.log(response);
    //add member to list
    const response = await mailchimp.lists.addListMember("20b****bce", {

    console.log(response);

  run();

app.listen(3000, function() {
