Object Not Found

I have gone over this code a few times, but continue to get the same message: "The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error."

My code is below~ any help would be greatly appreciated as I have exhausted my deadline to complete my <Code> Louisville project building a website using Composer while integrating a database that collects contact form data!

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

/Instantiate a Slim Application/ $app = new \Slim\Slim( array( 'view' => new \Slim\Views\Twig() //Set the View Class to Twig ));

/TWIG Option to 'View'/ $view = $app->view(); $view->parserOptions = array( 'debug' => true ); $view->parserExtensions = array( new \Slim\Views\TwigExtension(), );

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

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

/POST Route for Contact Submission (Using Request VAR)/ $app->post('/contact', function() use($app){ $name = $app->request->post('name'); $email = $app->request->post('email'); $msg = $app->request->post('msg'); //Sanitize Filters if(!empty($name) && !empty($email) && !empty($message)) { $cleanName = filter_var($name, FILTER_SANITIZE_STRING); $cleanEmail = filter_var($email, FILTER_SANITIZE_EMAIL); $cleanMsg = filter_var($msg, FILTER_SANITIZE_STRING); } else { //Message User indicating 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 Website');
$message->setFrom(array(
    $cleanEmail => $cleanName
));

$message->setTo(array('principal@mistermoody.com' => 'Mister Moody'));
$message->setBody($cleanMsg);

$result = $mailer->send($message);  //Capyure output

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

});

$app->run();
