  • I encountered the same issue on one of my sites starting about last Friday, 2023-07-17. Looking through WooCommerce, it seems that they might be triggering a legacy version of the woocommerce_update_order action which excludes the 2nd parameter, $order. This is definitely not ideal, but the temporary fix I’ve done is to edit includes/class-mailchimp-woocommerce-service.php to not require the $order parameter as such:

    public function handleOrderUpdate($order_id, $order = null) { // Default $order to null
    if (is_null($order)) $order = new \WC_Order($order_id); // If $order is null, create from provided $order_id
    mailchimp_log('handleOrderUpdate', 'order_status');
    $this->handleOrderSaved($order_id, $order, true);
}

    I did the same for handleOrderCreate as well just in case. It would definitely be better to have a permanent fix for this in the next update of this plugin.
