I'm trying duplicate the sample code found here: https://www.docusign.com/p/APIGuide/APIGuide.htm#Sending%20Group/Create%20and%20Send.htm
I copied the C# code to build the envelope and only adjusted for my environment.. sample file, email address etc. When I execute this I get the following exception:
A processing error occurred: System.ServiceModel.FaultException: The request contained at least one invalid parameter. Guid cannot be null.
Server stack trace: at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Has anyone seen this issue? I've looked over the Envelope, Recipient, Document, and Tab types on the API reference and I don't see any field that is a guid.
