Hi,

I have a webshop running on Umbraco 9.5.4 and Vendr 2.3.4.

I use the OrderFinalizedHandler to add invoice numbers to orders and orderlines and to be displayed in the order email.

Both works...But only sometimes.

I have added Auto Capture in our payment method (QuickPay).

When creating an Uow the invoice numbers are only saved to the orders for the most part. Some times the invoice number isn't added.

We have made sure, its only running once and only is the invoicenumber is null. I've tried using OrderTransactionUpdatedHandler instead - but this fails when trying to send a mail with _vendrApi.SendEmail.

Any ideas what to do? I can see in the log files that the code is running, but nothing is saved to the order property.

The code is the following.

                    using (IUnitOfWork uow = _vendrApi.Uow.Create())
                {
                    Order order = orderReadOnly
                        .AsWritable(uow)
                        .SetProperties(new Dictionary<string, string>
                        {
                            { "invoiceNumber", _orderHelper.GenerateInvoiceNumber() }
                        });
                    _vendrApi.SaveOrder(order);

                    Serilog.Log.Information($"Added invoice number on order {order.Properties["invoiceNumber"]}");

                    int orderlineCounter = 1;
                    foreach (var orderline in order.OrderLines)
                    {
                        var orderlineNumbering = orderlineCounter.ToString().PadLeft(3, '0');
                        var orderLineID = order.Properties["invoiceNumber"] + "_" + orderlineNumbering;

                        Serilog.Log.Information($"OrderLineId {orderLineID}");

                        order.WithOrderLine(orderline.Id).SetProperty("OrderLineID", orderLineID);
                        _vendrApi.SaveOrder(order);
                        orderlineCounter++;
                    }

                    uow.Complete();

                    Serilog.Log.Information("Exiting CreateInvoice");
