Ship Station Export

[tripleW]

A GoldR10 SR1 site is getting this error when trying to export orders to Ship Station:

Object reference not set to an instance of an object.
Exception: Object reference not set to an instance of an object. Stack Trace: at CommerceBuilder.Services.ShipStation.ShipStationService.CreateOrder(OrderShipment shipment) at CommerceBuilder.DataExchange.ShipStationExportManager.a(ShipStationExportOptions A_0)

Any ideas as to what would cause this?

Thanks

I just checked the R12 source code vs. the R10 source code and there are 4 null checks in R12 that aren't there in R10.
