Lumen Illuminate Http Client Request unresolvable dependency

I'm trying to store a data via POST method using Laravel\Lumen with Eloquent. The database I'm using is MySQL.

Heres my CategoriesController.php:

<?php

namespace App\Http\Controllers;

use App\Category;
use Illuminate\Http\Client\Request;

class CategoriesController extends Controller
{
    public function index()
    {
        return Category::all();
    }

    public function create(Request $request)
    {
        return response()
            ->json(
                Category::create(['description' => $request->description]),
                201
            );
    }
}

Here's my CategoryModel.php:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    protected $fillable = ['description'];

    public function expense()
    {
        return $this->belongsTo(Expense::class);
    }
}

In my App.php file I've uncommented the lines:

$app->withFacades();
$app->withEloquent();

My Web.php file:

$router->group(['prefix' => 'api'], function ($router){
   

    $router->get('categories', 'CategoriesController@index');
    $router->post('categories', 'CategoriesController@create');
});

Via Postman I'm sending the following post request:

{
        "description" : "teste"
}

After the request was sented I'm having the 500 HTTP Status Response. The error contains the following StackTrace:

BindingResolutionException HTTP 500 Internal Server Error

        {
            $message = "Unresolvable dependency resolving [$parameter] in class {$parameter->getDeclaringClass()->getName()}";
            throw new BindingResolutionException($message);
        }
