Adding the repository to construct gives user deprecated error

I have following lines of code in my controller.

<?php

namespace App\Controller;

use App\Repository\TaskListRepository;
use FOS\RestBundle\Controller\AbstractFOSRestController;

class ListController extends AbstractFOSRestController
{
    /**
     * @var TaskListRepository
     */
    private $taskListRepository;

    public function __construct(TaskListRepository $taskListRepository)
    {
        $this->taskListRepository = $taskListRepository;
    }

    /**
     * @Route("/lists", name="lists")
     */
    public function getListsAction()
    {
        return $this->taskListRepository->findAll();
    }

}

When I try to debug route, I am getting following error:

[info] User Deprecated: Using the WebserverBundle is deprecated since Symfony 4.4. The new Symfony local server has more features, you can use it instead. 2019-12-16T04:37:53+01:00 [info] User Deprecated: Loading the file "../../src/Controller/" from the global resource directory "D:\xampp\htdocs\symfony_rest\src" is depre cated since Symfony 4.4 and will be removed in 5.0.

How can I fix this issue?
