Hello, We want to buy this plugin and we instaled trial version. Unfortunately tere is a bug in the Attachments 4.20 plugin. In MessageTokensAddedEventConsumer.HandleEvent you are getting the order ID from “Order.OrderNumber“ token. In our case, order number is very different from actual order ID in DB and it is also too big to even fit in a 32-bit integer. Therefore sending e-mail doesn’t work for us since int.TryParse always returns false.
This can easily be fixed if you get order ID from “Order.OrderId“ token instead of from “Order.OrderNumber“.
