WooCommerce forestall execution of webhook for brand spanking new orders which gadgets are in sure class

Hello guys I have been puzzled by this situation for two days now and I can not discover a option to make it working. I’ve WooCommerce webhook triggered when new Order is created, however I need to forestall execution for orders which gadgets are in sure classes. I am making an attempt to attain this by utilizing the woocommerce_webhook_should_deliver filter-hook. Right here is my try and I will clarify the difficulty with it:

perform custom_woocommerce_webhook_should_deliver($shouldDeliver, $occasion, $arg) {
    $excludeCategories = [16, 17];
    $order = wc_get_order($arg);
    $logger = wc_get_logger();

    foreach ($order->get_items() as $item_id => $merchandise) {
        $term_ids = wp_get_post_terms(
            $item->get_product_id(), 'product_cat', array('fields' => 'ids')
        );
        $consequence = array_diff($excludeCategories, $term_ids);

        $logger->add(
            sprintf(
                "send-order-debug-%s",
                (int)$arg
            ), json_encode(['res' => $result, 'ids' => $term_ids])
        );
        if (depend($excludeCategories) !== depend($consequence)) {
            $shouldDeliver = false;
            break;
        }
    }

    $logger->add(
        sprintf(
            "send-order-debug-%s",
            (int)$arg
        ),
        json_encode(
            [
                'shouldDeliver' => (int)$shouldDeliver,
                'itemsCount' => count($order->get_items()),
            ]
        )
    );

    return $shouldDeliver;
}

add_filter('woocommerce_webhook_should_deliver', 'custom_woocommerce_webhook_should_deliver', 10, 3);

As you may see what I am doing is to get the order and attempt to forestall the webhook execution if there are gadgets in 2 classes(hardcoded within the instance). The issue and for my massive shock is that within the second of this examine $order->get_items() returns empty array, thus my filter at all times returns true. Right here is the log I’ve put on the finish of the tactic.

{"shouldDeliver":1,"itemsCount":0}

The attention-grabbing factor right here to know is that there’s nothing mistaken with the order content material, it is not empty and when webhook is executed I obtain the order with it is gadgets.

I am not a WooCommerce/WordPress guru and I do not know what’s the method of saving orders and the order gadgets, however I assume that within the second I get on this filter, order gadgets are nonetheless not created. Anybody can provide me some concepts of the way to make this working? I am open to completely totally different strategy of fixing this job(please with out nugatory assumptions, solely examined and dealing examples). Thanks upfront!
