REST API hook for add new value (product image) to "line_items" in order response for simple product and variable product both

Also Use for multiple products

function get_product_order_image( $response, $object, $request ) {    if( empty( $response->data ) )        return $response;            $images = array();        foreach($response->data['line_items'] as $key => $productItems){        $productID = $productItems['product_id'];        $variationID = $productItems['variation_id'];                if($variationID == 0){            $thumbnailID = get_post_meta( $productID, '_thumbnail_id', true);            $attachment = wp_get_attachment_image_src($thumbnailID, 'woocommerce_thumbnail' );            $image = $attachment[0];        }else{            $variation = new WC_Product_Variation( $variationID );            $image_id = $variation->get_image_id();            $attachment = wp_get_attachment_image_src($image_id, 'woocommerce_thumbnail' );            $image = $attachment[0];        }                $response->data['line_items'][$key]['image'] = $image;        }         return $response;} add_filter( "woocommerce_rest_prepare_shop_order_object", "get_product_order_image", 10, 3 );
