ERROR 500 Stripe Webhook when payment_intent.created on Laravel

I'm trying the cmd commands to listen the Stripe webhooks (https://stripe.com/docs/webhooks/test). https://i.stack.imgur.com/1X5NB.png

this is the route web.php:

use Illuminate\Http\Request;
Route::post('webhook/payment/succeeded', function (Request $request){
    if($request->type === "payment_intent.created"){
        try{
Payment::create([
    'stripe_id' => $request->data['object']['id'],
    'amount' => $request->data['object']['amount'],
]);
        } catch (\Exception $e) {
            return $e->getMessage();
        }
    }
    return 'ok';
});

this is the Payment.php :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Payment extends Model
{
    use HasFactory;
    protected $guarded = [];

}

So please how to fix that ??
