Symptoms

For every call made to WorkflowManagementServer.GetActionInstanceRights, 2 errors are logged in the HostServer log.
The calls return successfully, but my event viewer log and Hostserver logs are getting bloated with these errors:

Here are the errors being generated each time the API call is made:
"1028903","2016-12-23 08:58:42","Error","System","2025","InternalMarshalError","SourceCode.Hosting.Server.Runtime.HostServerBroker.InternalMarshal","2025 Error Marshalling SourceCode.Security.UserRoleManager.Runtime.UserRoleManagerServer.FormatItemName, data parameter cannot be nul or empty","","","usgr-devk2bp1:D:Program Files (x86)K2 blackpearlHost ServerBin","1028903","41e1917f7a494fd0a91a1f98f4fe901f",""

"1028904","2016-12-23 08:58:42","Error","Communication","8130","ConnectionPacketError","SourceCode.SocketService.Legacy::HandlePacket","8130 Error processing message from 10.200.106.24:60650: data parameter cannot be nul or empty","","","usgr-devk2bp1:D:Program Files (x86)K2 blackpearlHost ServerBin","1028904","14d740bfc32446f3ac7c8ab90e6b9a46",""
 

Diagnoses

The call is successful, but the logging of these errors fills up the log files. This was identified as a bug.
