• I've read the contribution guidelines!

Expected Behaviour

Rhino:
If you add a stream with no objects, it should show up in the Speckle pane, so that when objects do get added they can be easily pulled in.

GH:
If you add a stream with no objects, the Receiver should run without errors and simply produce no output.

Actual Behaviour

Adding a speckle stream with no objects in Rhino results in nothing happenning.

In GH, the following error occurs:

Affected Projects

SpeckleRhino in both Rhino and GH. maybe it is an issue in SpeckleUIApp or the SpeckleServer?

Reproduction Steps & System Config (win, osx, web, etc.)

1. Create a stream, but don't add any objects.
   2a. Try to add this stream to Rhino.
   2b. Pass the stream id to a GH Receiver component.

Proposed Solution (if any)

Find out where the error is occuring and update the client behaviour.
