Problem

I have tried printing a Deutsche Post shipping label and am seeing an error returned:

Value '' is not one of declared properties for field 'shipmentNaturetype'

Solution

The error is being returned because there is no value for Shipment Type. You can either set a default value for shipment type in Linnworks.net > Shipping > Integrations > Config for Deutsche Post, or set a service specific value in Integrations > Services > Edit screen.
