Contact Form using Node.js is failing

I'm new to Node so I apologize in advance if my code is not tidy. I'm trying to create a contact form using node. I'm really close but when I send the form it fails. I get an error of "Invalid Captcha" in the console. Below is my code I took out the sensitive data.

//app.js
pp.set('view engine', 'ejs');

app.locals.pagetitle = '';

app.use(express.static('public'));
app.use(bodyParser.raw());  
app.get('/', routes.index);
app.get('/portfolio', routes.portfolio);
app.get('/contact', routes.contact);

app.get('*', function(req, res){
res.send('Bad Route');
});

//Require the module
var nodemailer = require('nodemailer');

//Create the reusable transport
var transporter = nodemailer.createTransport({
    service: 'Gmail',
    auth: {
       user: 'myEmailAddress',
       pass: 'myPassword'
    }
});
var sweetcaptcha = new require('sweetcaptcha')(appId, appKey, appSecret);
console.log( req.body, req.params );

  //Validate captcha
  sweetcaptcha.api('check', {sckey: req.body["sckey"], scvalue: req.body["scvalue"]}, function(err, response){
  if (err) return console.log(err);

  if (response === 'true') {
     // valid captcha

     // setup e-mail data with unicode symbols
     var mailOptions = {
        from: 'name <yourEmail@email.com>', // sender address
        to: 'myEmail@gmail.com', // list of receivers. This is whoever you want to get the email when someone hits submit
        subject: 'New email from your website contact form', // Subject line
        text: req.body["contact-form-message"] + ' You may contact this sender at: ' + req.body["contact-form-mail"] // plaintext body

     };

     // send mail with defined transport object
     transporter.sendMail(mailOptions, function (error, info) {
        if (error) {
           console.log(error);
        } else {
           console.log('Message sent: ' + info.response);
        }
     });
     //Success
     res.send("Thanks! We have sent your message.");

  }
  if (response === 'false'){
     // invalid captcha
     console.log("Invalid Captcha");
     res.send("Try again");

  }
  });

});

//index.js
exports.index =  function(req, res){
res.render('default', {
    title: 'Home',
    classname: 'home',
    users: ['Alex', 'Brandon', 'Vanessa']
});
 };

 exports.portfolio = function(req, res){
res.render('default', {
    title: 'Portfolio',
    classname: 'portfolio'
});
 };
   exports.contact = function(req, res){
  //Require the sweetcaptcha module and give it the credentials you were sent upon registration.
var sweetcaptcha = new require('sweetcaptcha')(appId, appKey, appSecret);
sweetcaptcha.api('get_html', function(err,html) {
    res.render('contact', {
        title: 'Contact',
        classname: 'contact',
        captcha: html
    });


});

};

//scripts.js
$(function(){
$(document).ready(function() {
    $("#contact-form-submit").click(function (e) {

        e.preventDefault(); // prevent page reload
        $.ajax({
            type: "POST",
            url: '/contact',
            data: $("#contact-form").serialize(),
            contentType: "application/x-www-form-urlencoded; charset=UTF-8",
            success: function (response) {
                $("#submitResponse").html(response);
            }
        });
    });


});


});

Hopefully this is clear I know I copied and pasted a lot of code. Please ask any follow up questions if it is not. Thanks.
