Issue with "decoration"

[igs3000]

The Netsimulyzer documentation shows the following way to use the "decoration" feature

auto decoration = CreateObjectnetsimulyzer::Decoration(/* the orchestrator */);
decoration.SetAttribute ("Model", StringValue ("path/model.obj"));
decoration.SetAttribute ("Height", DoubleValue (2.0));

But if we try to set a 3D object as decoration it ends with following error:,

error: ‘class ns3::Ptrns3::netsimulyzer::Decoration’ has no member named ‘SetAttribute’
decoration.SetAttribute ("Model", StringValue("mymodel.obj"));

Then I managed to run it by using decoration-> reference operator as follows :

auto decoration = CreateObjectnetsimulyzer::Decoration(orchestrator);
decoration->SetAttribute ("Model", StringValue("mount.blend1.obj"));
decoration->SetPosition ({0.0,0.0,0.0});
//decoration->SetAttribute ("Height", DoubleValue (0));
decoration->SetAttribute ("Scale" , DoubleValue (100));

Now if I comment the “Height” attribute setting line, then it works and opened the model in the visualizer.
But if I uncomment the line “Height” attribute setting line, then the compiler ends with following error: (In fact, as document says, I am trying to change height before changing the scale.

Build failed
-> task in 'mytestsimulation failed with exit status 1 (run with -v to display more information)

Why the 'decoration.SetAttribute. is not working? (dot)
Why adjusting height of the decorative 3D model is not working?.
