Powershell orion.container createcontainer fails

Hi

I'm using Powershell v3 with the orion SDK V1.10

When I try do a group create with the SDK I get an "Object reference not set to an instance of an object." error

I've enabled the debugging but can't see what the issue is.  can anyone maybe shed some light for me.
