Non-generic GetView with a view that uses a reduce function

Hi, I'm new to Couchbase and I'm having a little trouble using the non-generic GetView in the 1.2 .NET Library. I'm using the example Beer class shown here http://www.couchbase.com/develop/net/next, and my view function is:

function (doc) {
  if(doc.type == 'beer')
    {
       emit([doc.brewery, doc.name], null);
    }
}

With a _count reduce using group level 1.

And here is the code to get the view and iterate through it.

var view = client.GetView("beers", "by_brewery_and_name").GroupAt(1).Group(true);
 
foreach (var row in view)
{
   // do something
}

When I go to run the code it throws an unhandled exception:

Unhandled Exception: System.InvalidOperationException: The value 'id' was not found in the row definition. at Couchbase.CouchbaseView.__Row..ctor(CouchbaseView owner, IDictionary`2 row) in C:\dev\couchbase-net-client-build\src\Couchbase\CouchbaseView.cs:line 49 at Couchbase.CouchbaseView.b__0(JsonReader jr) in C:\dev\couchbase-net-client-build\src\Couchbase\CouchbaseView.cs:line 29 at Couchbase.CouchbaseViewBase`1.d__0`1.MoveNext() in C:\dev\couchbase-net-client-build\src\Couchbase\CouchbaseViewBase.cs:line 104

Am I doing something wrong? Or can you not iterate through an IView that uses a reduce function?
