I am trying to redirect in my controller_action_predispatch observer. However, I got http 500 error, unable to handle the request

Note: I got the error 500 once i include \Magento\Framework\App\Response\Http $http (even if i don't do the redirect logic inside)

What could be the problem?

namespace Vendor\Name\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class RedirectObserver implements ObserverInterface
    protected $accountRedirect;
    protected $session;
    protected $url;
    protected $http;

    public function __construct(
        \Magento\Customer\Model\Account\Redirect $accountRedirect,
        \Magento\Customer\Model\Session $session,
        \Magento\Framework\UrlInterface $url,
        \Magento\Framework\App\Response\Http $http
    ) {
        $this->accountRedirect = $accountRedirect;
        $this->session = $session;
        $this->url = $url;
        $this->http = $http;

    public function execute(Observer $observer)
        if (!$this->session->isLoggedIn()) {
            // redirect to login page
            $this->http->setRedirect($this->url->getUrl('customer/account/login'), 301);

Should try with

 <preference for="Magento\Framework\App\Response\RedirectInterface" type="Magento\Store\App\Response\Redirect" />

Magento\Framework\App\Response\RedirectInterface or Magento\Store\App\Response\Redirect. A good example Magento 2 - Redirect user to a specific page if not logged in

  • I tried the sample given with \Magento\Framework\App\Response\RedirectInterface on controller action predispatch observe but not working. still http error 500. Should i add the preference for it to work? Where should i add the preference in. Commented Feb 1, 2018 at 4:07
  • I'm pretty sure the link I gave you it will work. Please, check other parts. Commented Feb 1, 2018 at 4:09
  • No, I just show you the preference. Don't to do anything with it. Commented Feb 1, 2018 at 4:10
  • It works after i remove all the var/pub folder and static deploy again. Do i have to do it all the time? I am in developer mode. Commented Feb 1, 2018 at 6:54
  • Don't need to do static deploy every time in developer mode. Just delete pub/static, not delete .htaccess. And then refresh the page again. The static content will be generated on fly and symlink. Commented Feb 2, 2018 at 1:50
