No query results for model [App\Category].

I am getting this error when simply trying to view a page, all the controller does is return a view with some seeded information.

web.php

 // ADMIN -------------

 Route::group(['namespace' => 'Admin', 'middleware' => ['auth'], 'prefix' => 'admin'], function()
 {

 Route::get('home', function(){
    return view('admin.home');
});

 Route::resource('category', 'CategoryController');

 Route::resource('products', 'ProductController');

 Route::resource('user', 'UserController');

 Route::get('orders', [
    'as' => 'admin.order.index',
    'uses' => 'OrderController@index'
]);

 Route::post('order/get-items', [
    'as' => 'admin.order.getItems',
    'uses' => 'OrderController@getItems'
]);

 Route::get('order/{id}', [
    'as' => 'admin.order.destroy',
    'uses' => 'OrderController@destroy'
]);

 Route::get('category/create', [
'as' => 'admin.category.create',
'uses' => 'CategoryController@create'

]);

 Route::get('category/store', [
'as' => 'admin.category.store',
'uses' => 'CategoryController@store'
]);

 Route::get('category/index', [
'as' => 'admin.category.index',
'uses' => 'CategoryController@index'
]);

 Route::get('category/edit', [
'as' => 'admin.category.edit',
'uses' => 'CategoryController@edit'
]);
 });

The functions on Categorycontrollers;

  public function index()
    {
    $categories = Category::all();
    //dd($categories);
    return view('admin.category.index', compact('categories'));
    }

    public function create()
    {
    return view('admin.category.create');
    }

   public function store(Request $request)
   {
    //return $request->all();


    $this->validate($request, [
      'name' => 'required|unique:categories|max:255',
    ]);
    
    $category = category::create([
        'name' => $request->get('name'),
        'slug' => str_slug($request->get('name')),
        'description' => $request->get('description'),
        
    ]);
    
    $message = $category ? 'Categoría agregada correctamente!' : 'La Categoría NO pudo agregarse!';
    
      return redirect()->route('admin.category.index')->with('message', $message);
    }

    public function show(Category $category)
    {
    return $category;
    }

    public function edit(Category $category)
    {
    return view('admin.category.edit', compact('category'));
    }

edit.blade

  Form::model($category, array('route' => array('category.update', $category->id))) 

index.blade

  <a href="{{ route('admin.category.edit',['id' => $category->id]) }}" class="btn btn-primary"><i class="fa fa-pencil-square"></i></a>

When I give it to edit, I redirect to that address;

http://127.0.0.1:8000/admin/category/edit?id=1

but I get the error.
