laravel - 试图在雄辩的多态中访问 null 类型值的数组偏移量

Question

class Product extends Model
{
    use HasFactory;

    protected $fillable = [
        'productName',
        'quantity',
        'weight',
        'boxes',
        'MRP',
        'costprice',
        'productDescription',
        'seller_id',
        'category_id'
    ];

    public function image()
    {
        return $this->morphOne(Image::class,'imageable');
    }
}

class Image extends Model
{
    use HasFactory;

    protected $fillable = [
        'url',
        'size',
        'filename',
        'imageable_id',
        'imageable_type',
    ];

    public function imageable()
    {
        return $this->morphTo();
    }
}

class ProductController extends Controller 
{
    function index()
    {
        $product = Product::with('image')->get(); 

        return view('layouts.ecommerce.productAvailable', compact('product'));
    }
}

<!---------productAvailable.blade.php--------------
@foreach($product as $key => $val) 
    <td>{{ $val['image']['id'] }}</td>
@endforeach

我无法遍历关系，但是当我使用 $val['image'] 它返回一个集合

@foreach($product as $key => $val) 
    <td>{{ $val['image'] }}</td>
@endforeach
