502 bad gateway error when sending message.

When I submit the forum the screen attempts to load for about 15 seconds then returns a screen with 502 bad gateway error. I have looked over my code for issues and was unable to find something that would cause this. I have posted the code below thank you for your help.

<?php 

require 'vendor/autoload.php';

$app = new \Slim\Slim( array(
  'view' => new \Slim\Views\Twig()
));


$view = $app->view();
$view->parserOptions = array(
    'debug' => true,
);

$view->parserExtensions = array(
    new \Slim\Views\TwigExtension(),
);

$app->get("/", function() use($app){
  $app->render('about.twig');
})->name('home');

$app->get("/contact", function() use($app){
  $app->render('contact.twig');
})->name('contact');

$app->post("/contact", function() use($app){
  $name = $app->request->post('name');
  $email = $app->request->post('email');
  $msg = $app->request->post('msg');

  if(!empty($name) && !empty($email) && !empty($msg)){
    $cleanName =filter_var($name, FILTER_SANITIZE_STRING);
    $cleanEmail =filter_var($email, FILTER_SANITIZE_EMAIL);
    $cleanMsg =filter_var($msg, FILTER_SANITIZE_STRING);
  } else{
    //message the usere there was a problem
    $app->redirect('/contact');
  }

  $transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');
  $mailer = \Swift_Mailer::newInstance($transport);

  $message = \Swift_Message::newInstance();
  $message->setSubject('Email From Our Website');
  $message->setFrom(array(
     $cleanEmail => $cleanName
  ));
  $message->setTo(array('treehouse@localhost'));
  $messge->setBody($cleanMsg);

  $result = $mailer->send($message);

  if($result > 0) {
    //send thank you messege
    $app->redirect('/');
  } else {
    //send message to user that failed to send
    //log that there was an error
    $app->redirect('/contact');
  }
});

Ok, I got this to work in a branch of my attempt of the same tutorial. The main prob I noticed is that you need to run the app (see bottom) also a misspelling where you set the: $messge->setBody($cleanMsg); instead of: $message->setBody($cleanMsg);

I also noted that the:
date_default_timezone_set('America/New_York'); was missing from the top of the page..

(you'll see where I used redirects to tell me where the "break" was. A good trick is to put redirects after large chunks of code and set the variable in question inside like so: $app->redirect($variable); this will break the site but return the variable as the site is seeing it.)

See included:

<?php 
date_default_timezone_set('America/New_York');    //*************missing************
require 'vendor/autoload.php';


$app = new \Slim\Slim( array(
  'view' => new \Slim\Views\Twig()
));


$view = $app->view();
$view->parserOptions = array(
    'debug' => true,
);

$view->parserExtensions = array(
    new \Slim\Views\TwigExtension(),
);

$app->get("/", function() use($app){
  $app->render('about.twig');
})->name('home');

$app->get("/contact", function() use($app){
  $app->render('contact.twig');
})->name('contact');

$app->post("/contact", function() use($app){
  $name = $app->request->post('name');
  $email = $app->request->post('email');
  $msg = $app->request->post('msg');

  if(!empty($name) && !empty($email) && !empty($msg)){
    $cleanName =filter_var($name, FILTER_SANITIZE_STRING);
    $cleanEmail =filter_var($email, FILTER_SANITIZE_EMAIL);
    $cleanMsg =filter_var($msg, FILTER_SANITIZE_STRING);

  } else{
    //message the usere there was a problem
    $app->redirect('/message filter problem');   // *******used redirect as a debugger**********
  }

  $transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');
  $mailer = \Swift_Mailer::newInstance($transport);

  $message = \Swift_Message::newInstance();
  $message->setSubject('Email From Our Website');
  $message->setFrom(array(
     $cleanEmail => $cleanName
  ));
  $message->setTo(array('treehouse@localhost'));
  $message->setBody($cleanMsg);                   // ************spelled message as mssge**********

  $result = $mailer->send($message);

  if($result > 0) {
    //send thank you messege
    $app->redirect('message_sent');   //*******used redirect as a debugger ******
  } else {
    //send message to user that failed to send
    //log that there was an error
    $app->redirect('message_not_sent');     // *******used redirect as a debugger*********
  }
});

$app->run();                                         //************** missing************
?>```
