Error when sending email using nodemailer - node.js

Question

I'm trying to set up nodemailer for an app I'm creating. I'm receiving an error when I try and run the code.
This is my setup:
const nodemailer = require("nodemailer");
const xoauth2 = require("xoauth2");
var transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
xoauth2: xoauth2.createXOAuth2Generator({
user: '****#gmail.com',
clientId: '*******************************',
clientSecret: '*****************************',
refreshToken: '*****************************'
})
}
});
var mailOptions = {
from: 'Dave <*******#gmail.com>',
to: '*******#gmail.com',
subject: 'Nodemailer test',
text: 'Hello world'
}
transporter.sendMail(mailOptions, function(err, res) {
if (err) {
console.log(err);
} else {
console.log('Email sent');
}
})
Obviously, I've double checked my client ID, secret and refresh token. But I get the following error:
{ Error: Invalid login: 535-5.7.8 Username and Password not accepted. Learn more at

This is the first time I've tried using nodemailer and I feel I'm obviously missing a key piece here but not sure what.
New error when using real email and password:

Answer 1

You need to set up the transporter differently, using the actual email and password of a real Google Account.
// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'somerealemailaddress#gmail.com', //email address to send from
pass: 'somerealemailpassword' //the actual password for that account
}
});

const xoauth2 = require("xoauth2");
Actually in my case i didn't make use of the above code which i have mentioned and yet it worked fine...Just changed the google settings from the link sent in the error and it was fine.
But i get the error especially when i try to use yahoo as the service provider instead of google.I have attached a screenshot of the error which i get for your reference.
