I was trying to send an email from my nodejs server using the nodemailer and OAuth 2 from a web app I'm working on
The code was fine and the mails were being sent as they should be but today when I tried to send mails this error occurred on the server-side as the front end was working fine.
This is my server code:
const express = require('express')
const app = express()
const bodyParser = require('body-parser')
const hb = require('nodemailer-express-handlebars')
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json())
const nodemailer = require('nodemailer');
const { google } = require('googleapis');
const path = require('path');
// These id's and secrets should come from .env file.
const CLIENT_ID = 'client i_d';
const CLEINT_SECRET = 'client secret';
const REDIRECT_URI = 'https://developers.google.com/oauthplayground';
const REFRESH_TOKEN = 'refresh token**strong text**';
const oAuth2Client = new google.auth.OAuth2(
CLIENT_ID,
CLEINT_SECRET,
REDIRECT_URI
);
oAuth2Client.setCredentials({ refresh_token: REFRESH_TOKEN });
//query ajaxx
app.post("/query", async (req,res) =>{
try{
const accessToken = await oAuth2Client.getAccessToken();
const transport = nodemailer.createTransport({
service: 'gmail',
auth: {
type: 'OAuth2',
user: 'ummed.gagrana@gmail.com',
clientId: CLIENT_ID,
clientSecret: CLEINT_SECRET,
refreshToken: REFRESH_TOKEN,
accessToken: accessToken,
},
})
const handlebarOptions = {
viewEngine: {
extName: ".handlebars",
partialsDir: path.resolve(__dirname, "emailTemplate"),
defaultLayout: false,
},
viewPath: path.resolve(__dirname, "emailTemplate"),
extName: ".handlebars",
};
transport.use(
"compile",
hb(handlebarOptions)
);
// the data which we gonna send
const responseMail = {
from: "The Ummed Gagrana"+'<ummed.gagrana@gmail.com>',
to: req.body.user.Qemail,
subject: "We will get back to you soon!!",
// html: '<h2>From:</h2>'+'<h4>'+req.body.email+"</h4> <br>"+"<h2>Message:</h2>"+'<h4>'+req.body.message+"</h4>",
template: 'comeBack',
context: { // <=
name: req.body.user.Qname,
}
};
const receiveMail = {
from: req.body.email+"<ummed.gagrana@gmail.com>",
to: "ummed.gagrana@gmail.com",
subject: "Room enquiry",
template:'query',
context: {
// user details

//the query details
accomodation: req.body.query.room,

budget: req.body.query.budget
}
}
//sending mail
const Sresult = await transport.sendMail(responseMail);
const Rresult = await transport.sendMail(receiveMail);
// checking the result after sending mail
console.log(Sresult)
console.log(Rresult)
res.send({datapassed:"We have received your query!"})
} catch (error) {
console.log(error)
res.send({datapassed:"There was some error try again later"})
}
})
//contact ajax
app.post("/api", async (req,res) => {
try{
const accessToken = await oAuth2Client.getAccessToken();
const transport = nodemailer.createTransport({
service: 'gmail',
auth: {
type: 'OAuth2',
user: 'ummed.gagrana@gmail.com',
clientId: CLIENT_ID,
clientSecret: CLEINT_SECRET,
refreshToken: REFRESH_TOKEN,

app.listen(3000, () => {
console.log("server up and running on port 3000")

The client id and the refresh tokens are all correct I've tried to refresh the refresh token but still getting the same error I will show you the full log of the error
I really don't have any idea what am I missing it would be a great help and please ignore my untidy code I'm a beginner thank you
