Notify Slack send Array - laravel

Question

im trying to send some values from a DB with Notify to Slack. Somehow every time I load my Website the only message I get is "Array" and not the data from the DB.
This is my Notifications .php
class InventoryReStock extends Notification
{
use Queueable;
/**
* Create a new notification instance.
*
* #return void
*/
public function __construct($reorder)
{
$this->reorder = $reorder;
}
/**
* Get the notification's delivery channels.
*
* #param mixed $notifiable
* #return array
*/
public function via($notifiable)
{
return ['slack'];
}
/**
* Get the mail representation of the notification.
*
* #param mixed $notifiable
* #return \Illuminate\Notifications\Messages\MailMessage
*/
public function toSlack($notifiable)
{
return (new SlackMessage)
->content([$this->reorder]);
}
This is the function that Im using on my controller to get the data form the Db
public function index()
{
//shows all the products in the database in an overview
$products = Product::all()->toArray();
$reord = Product::select('Product_Name')->where('Number_Runs', '<=', '5')->get();
$reorder = json_decode(json_encode($reord), true);
Notification::route('slack', 'https://hooks.slack.com/services/..../...../......')->notify(new InventoryReStock($reorder));
return view('products.lab_inventory_overview', compact('products', 'reorder'));
}
and this is my User.php
public function routeNotificationForSlack($notification)
{
Return 'https://hooks.slack.com/services/..../...../......';
}

Never mind, I found a solution . Just converting the array to string makes it work.
$reorder = implode(', ', array_flatten($reorde));
