How to solve autowire problem in symfony 5.3.10?-CodePudding

As you can see in the code below, when I am trying to delete my category. It's give me following errors:

Cannot autowire argument $category of "App\Controller\AdminController::deleteCategory()": it references class "App\Entity\Category" but no such service exists.

This is the code of function I have created in AdminController.php:

<?php

namespace App\Controller;

use App\Utils\CategoryTreeAdminList;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

use Symfony\Component\HttpFoundation\Response;

use Symfony\Component\Routing\Annotation\Route;

use App\Entity\Category;

#[Route('/admin')]

class AdminController extends AbstractController {

#[Route('/delete-category/{id}', name: 'delete_category')]

public function deleteCategory(Category $category): Response
{
    $entityManager = $this->getDoctrine()->getManager();
    $entityManager->remove($category);
    $entityManager->flush();
    return $this->redirectToRoute('categories');
}

}

Following is the code where I have mentioned categoryList:

<?php

namespace App\Utils;

use App\Utils\AbstractClasses\CategoryTreeAbstract;

class CategoryTreeAdminList extends CategoryTreeAbstract {

public $html_1 = '<ul >';
public $html_2 = '<li><i ></i>  ';
public $html_3 = '<a href="';
public $html_4 = '">';
public $html_5 = '</a> <a onclick="return confirm(\'Are you sure?\');" href="';
public $html_6 = '">';
public $html_7 = '</a>';
public $html_8 = '</li>';
public $html_9 = '</ul>';


public function getCategoryList(array $categories_array)
{
    $this->categorylist .= $this->html_1;
    foreach ($categories_array as $value) {
        $url_edit = $this->urlgenerator->generate('edit_category', ['id' => $value['id']]);

        $url_delete = $this->urlgenerator->generate('delete_category', ['id' => $value['id']]);
        $this->categorylist .= $this->html_2 . $value['name'] . 
        $this->html_3 . $url_edit . $this->html_4 . ' Edit' . 
        $this->html_5 . $url_delete . $this->html_6 . 'Delete' . 
        $this->html_7;

        if (!empty($value['children'])) {
            $this->getCategoryList($value['children']);
        }

        $this->categorylist .= $this->html_8;
    }

    $this->categorylist .= $this->html_9;

    return $this->categorylist;
}

}

public function deleteCategory($id): Response
