                ->setImageFile($item->getProduct()->getSmallImage()) // image,small_image,thumbnail

                'regular_price'      => $product->getPrice(),
                'special_price'      => $product->getSpecialPrice(),

                'manufacturer'       => $product->getManufacturer(),
                'imageUrl'           => $imageUrl,
                'category'           => $product->getName(),
                'special_category'   => $product->getName(),
                'doll_category'      => $product->getName(),
                'stock_quantity'     => $product->getQty(),
                'name'               => $product->getName(),
                'price'              => $product->getPrice(),
                'sku'                => $product->getSku(),
                'size'               => $product->getAttributeText('size'),
                'swatch'             => $product->getAttributeText('color'),
                'trend'              => $product->getAttributeText('trend'),
                'quantity'           => (float) $item->getQtyOrdered(),
            );

            // or you can retrieve the product object
            $product[] = $item->getProduct();
        }
        $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/products.log');
        $logger = new \Zend\Log\Logger();
        $logger->addWriter($writer);
        $logger->info($products);
        print_r($data);exit;

Answer 1

try this

foreach ($order->getAllVisibleItems() as $item) {
     ////// your code
}

Answer 2

You can try like this:

$orderItems = $order->getAllItems();
foreach ($orderItems as $item) {
    if (!$item->getParentItem()) continue;
    // rest of work
}
