I want to add data in database in Laravel, but I get error.
This is my Error:
ArgumentCountError

Route::post('', [CategoriesController::class, 'store'])->name('admin.categories.store');
my page:
<form action="{{ route('admin.categories.store') }}" method="post">

my Contoller:
public function store(StoreRequest $request)
{
$validatedData = $request->validate();
$createdCategory = Category::create([

'slug' => $validatedData['slug'],
]);
if(!$createdCategory){
return back()->with('failed', 'Failed to Create Category.');
}
return back()->with('success', 'Success to Create Category.');
}
my Request:
<?php
namespace App\Http\Requests\Admin\Categories;
use Illuminate\Foundation\Http\FormRequest;
class StoreRequest extends FormRequest
{
/**

public function authorize()
