Node Error Mailer

Question

I use nodemailer in my Firebase Cloud functions to send mail when data is added to the real-time database.

The code:

const functions = require('firebase-functions');
const nodemailer = require('nodemailer');

const gmailEmail = '[e-mail]';
const gmailPassword = 'mypassword';

const mailTransport = nodemailer.createTransport({
  service: 'gmail',
  auth: {
  user: gmailEmail,
  password: gmailPassword
}
});

const APP_NAME = 'ABC In'

exports.salonCreatedAccount = functions.database.instance('abc-
in').ref('/abc/{def}').onCreate(event => {
const snapshot = event.data;
const val = snapshot.val()
console.log(val);

const email = val.email;
const displayname = val.name;

return sendconfirmationEmail(email, displayname);
});

function sendconfirmationEmail(email, displayName){
const mailOptions = {
  from: `${APP_NAME} <[e-mail]>`,
  to: email
};

mailOptions.subject = `Welcome to ${APP_NAME}!`;
mailOptions.text = `Some Text`;
return mailTransport.sendMail(mailOptions).then(() => {
  console.log(`New welcome mail sent to ${email}`);
});
}

I get the following error on execution. NOTE. I made sure that the email address and password are correct and there is no error.

Error:

How to fix it?

Answer 1

The same error was fixed from the local nodejs test application, to which
@Zaheen replied: Nodemailer with Gmail and NodeJS , part of his answer is copied here:

var smtpTransport = require('nodemailer-smtp-transport');

var transporter = nodemailer.createTransport(smtpTransport({
  service: 'gmail',
  host: 'smtp.gmail.com',
  auth: {
    user: '[e-mail]',
    pass: 'realpasswordforaboveaccount'
  }
}));

( BTW 2FactorAuth ).
nodemailer-smpt-transport, xoauth2 host auth {}.
