Cookie is not being set to the index.php but the doLogin.php only

Please help.. I have been stuck on the section for days. I am running the code on a local server(xampp)..but it does not seen to be working..The cookie is being set to the DoLogin.php and not in the index.php file...

here are the code snippets..

//Code for creating the jwt as per video

$expTime = time() + 9600; $jwt =\Firebase\JWT\JWT::encode([ 'iss'=>request()->getBaseUrl(), 'sub'=>"{$user['id']}", 'exp'=>$expTime, 'iat'=>time(), 'nbf'=>time(), 'is_admin'=>$user['role_ID']==1 ],getenv("SECRET_KEY"),'HS256');

$accessToken = new \Symfony\Component\HttpFoundation\Cookie('access_token',$jwt,$expTime,'/', getenv('COOKIE_DOMAIN'));

redirect('index.php',['cookies'=>[$accessToken]]);

//The code for the redirect function..

function redirect($path, $extra =[]){

    $response = \Symfony\Component\HttpFoundation\Response::create (null,\symfony\Component\HttpFoundation\Response::HTTP_FOUND, ['Location'=>'/UserAuthentication2/'.$path]);

     if(key_exists('cookies', $extra)){

        foreach ($extra['cookies'] as $cookie ) {    
             $response->headers->setCookie($cookie); 

         }
     } 
        $response->send();
        exit;

}

//The code on the index.php function.

if(request()->cookies->has('access_token')){ echo "You are Logged in";

       } 
       else { echo "You are not logged in";}
