Upload::make with orchid CRUD

[gaetandezeiraud]

I am very new to orchid (and laravel in general). I have a problem with an Upload form element. I have following the documentation here https://orchid.software/en/docs/field/#upload so:

Migration:

...
$table->string('images')->nullable();
...

Model:

...
use Orchid\Attachment\Attachable;
use Orchid\Attachment\Models\Attachment;
...

class ShopProduct extends Model
{
    use AsSource, Filterable, Attachable;

    protected $fillable = [
 ...
        'images',
...
    ];
    
    protected $cast = [
        'images' => 'array'
    ];
    
    public function photos()
    {
        return $this->hasMany(Attachment::class)->where('group','photo');
    }
}

Resource:

Upload::make('images')
                ->groups('photo')
                ->acceptedFiles('image/*')
                ->maxFiles(5),

But I don't understand why, when I tried to create a new product with images attached. I get the following error:

ErrorException
Array to string conversion

Without, it is working and create the product. And after I can add images without errors. But, when I try to edit later, the Upload is not pre-fulled with lasted images (uploaded earlier). And when I try to call the photos function (inside the model) like the following:

public function legend(): array
    {
        return [
            Sight::make('id'),
            Sight::make('name'),
            Sight::make('images')
                ->render(function ($model) {
                    var_dump($model->photos);
                    return;
                }):

I get this:

lluminate\Database\QueryException
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'attachments.shop_product_id' in 'where clause' (SQL: select * from `attachments` where `attachments`.`shop_product_id` = 1 and `attachments`.`shop_product_id` is not null and `group` = photo) (View: C:\laragon\www\creaboutique\vendor\orchid\platform\resources\views\layouts\legend.blade.php)

I think I have something wrong. But I can't seem to find
