Javascript – Google auth post request fails

I’m working an application where Google login (Oauth) callback fails. When I start the app, it redirects me to the Google Oauth’s login page. Below is the code:

passport.use(new GoogleStrategy({
  clientID: GOOGLE_CLIENT_ID,
  clientSecret: GOOGLE_CLIENT_SECRET,
  callbackURL: "http://localhost:8080/auth/google/callback"
},
function(accessToken, refreshToken, profile, done) {
    userProfile=profile;
    return done(null, userProfile);
}
));

app.get('/auth/google', 
  passport.authenticate('google', { scope : ['profile', 'email'] }));
 
app.get('/auth/google/callback', 
  
  // passport.authenticate('google', { failureRedirect: '/error' }),
  passport.authenticate('google'),
  function(req, res) {
    // Successful authentication, redirect success.
    var request = require("request");

    var options = {
      method: "POST",
      url: "http://localhost:8082/web/google-callback",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(userProfile),
    };
    request(options, function (error, response) {
      if (error) {
        console.log(error);
        return;
      }
      if (response.body != undefined){
        res.redirect('/select?t=' + JSON.parse(response.body)['token']);
      }
      else{
        res.redirect('/404');
      }    
    });    
});

After providing credential, callback fails and the response.body contains the following:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot POST /web/google-callback</pre>
</body>
</html>

As stated in the response body there is an error in body. The response.redirect implementation is:

res.redirect('/select?t=' + JSON.parse(response.body)['token']);

An leads in this direction will be of great help.
Thanks in advance.
