"Objects of Type $Extrusion are not supported"

I built from manager just this morning, see attached. I am just building a simple box in a blank file, so I don’t have anything to send in terms of a .3dm file. The error is happening in both Rhino 6 and in Rhino 7. I’m new to V2 so may have not completed the setup properly; all I’ve done was install the plugins via the manager and load up a server using the info found at the end of this thread: Unable to create speckle server using local host - #4 by dimitrie
