我是新的laravel，我试图提交表格到数据库，但我得到错误，我不知道为什么我已经添加了屏幕截图沿着与控制器，当我做dd($REQUEST->all())我得到的表格数据

<?php

namespace App\Http\Controllers;
use App\Inventory;
use Illuminate\Http\Request;

class InventoryController extends Controller
{
  public function index(){
    return view('invetory.index');
}
  public function sales(){
    return view('invetory.sale');
}
  public function create(Request $REQUEST){
    
// dd($REQUEST->all());
inventories::Create($REQUEST->all());
    
}
}

web.php

<?php

use Illuminate\Support\Facades\Route;

/*
