Why is nodemailer not sending mail?

Question

Node.js

Unable to send email: Error: connect ECONNREFUSED 127.0.0.1:465

require('dotenv').config()
const express = require('express')
const nodemailer = require('nodemailer')

const mailTransport = nodemailer.createTransport( {
    service: 'smtp.gmail.com',
    secure: false,
    port: 465,
    auth: {
        user: process.env.GMAIL_USER,
        pass: process.env.GMAIL_PASS
    }
})

mailTransport.sendMail({
    from: 'Text <[email protected]>',
    to: '[email protected]',
    subject: 'Text,
    text: 'Text text text '
}, function(err){
    if(err) console.error( 'Невозможно отправить письмо: ' + err );
})

PS The correct login and password come from the config

Answer 1

service: 'smtp.gmail.com' - replace with host: 'smtp.gmail.com'. The example was from an old book, after the update, the host property is used
