How to redirect from initController?

Hello! I have the following code:

PHP Code:

<?php namespace App\Controllers\Admin;

use App\Controllers\BaseController;

abstract class AdminController extends BaseController
{
    protected $helpers = ['form'];

    public function initController(
        \CodeIgniter\HTTP\RequestInterface $request,
        \CodeIgniter\HTTP\ResponseInterface $response,
        \Psr\Log\LoggerInterface $logger
    ) {
        parent::initController($request, $response, $logger);
        $user_id = session()->get('user_id');
        if (empty($user_id))
        {
            return redirect()->route('home');
        }
