SwiftMailer 's setFrom not working with variable - php

Question

I'm trying to send mail for a contact form locally by swiftmailer and gmail. I've checked every line and I know the problem is 'setFrom' .
$app->post('/contact', function ($request, $response, $args){
$body = $this->request->getParsedBody();
$name = $body['name'];
$email = $body['email'];
$msg = $body['msg'];
if(!empty($name) && !empty($email) && !empty($msg) ){
$cleanName = filter_var($name,FILTER_SANITIZE_STRING);
$cleanEmail = filter_var($name,FILTER_SANITIZE_EMAIL);
$cleanMsg = filter_var($name,FILTER_SANITIZE_STRING);
}else {
//redirecting to contact page
}
//sending email
$transporter = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
->setUsername('xxx#gmail.com')
->setPassword('xxx');
$mailer= \Swift_Mailer::newInstance($transporter);
$message = \Swift_Message::newInstance();
$message->setSubject('Email from our website');
$message->setTo(array('ns.falahian#gmail.com'));
$message->setBody($cleanMsg);
$message->setFrom([
$cleanEmail => $cleanName
]);
$result=$mailer->send($message);
if ($result > 0) {
$path = $this->get('router')->pathFor('home');
return $response->withRedirect($path);
} else {
$path = $this->get('router')->pathFor('contact');
return $response->withRedirect($path);
}
});
as you can see I also use Slim 3 framework. when I run the code I get this error:
Slim Application Error
A website error has occurred. Sorry for the temporary inconvenience.
But if I replace the $cleanEmail with 'x#y.z' the code works!
what should I do?
I know that by using gmail I can't change the sender name but I want to upload this code in a webhost and I don't want to get this issue there.
And can anyone suggest a better way for redirecting in Slim 3? Instead of these two lines:
$path = $this->get('router')->pathFor('contact');
return $response->withRedirect($path);
I've set names for my routes like this:
$app->get('/contact', function ($req, $res, $args) {
return $this->view->render($res, "contact.twig");
})->setName('contact');
thanks a lot!

You probably want to do the following instead.
$cleanEmail = filter_var($email,FILTER_SANITIZE_EMAIL);
$cleanMsg = filter_var($msg,FILTER_SANITIZE_STRING);
