Same Python script doesn't work in GhPython component

The following code is from the RhinoPythonPremerRev3.pdf page 47.

It can be executed via the Python editor in Rhino. However, it doesn't work in the GhPython component in Grasshopper with the following error message:

Runtime error (NotImplementedException): The method or operation is not implemented.
Traceback:
  line 180, in GetObject, "C:\Users\oat\AppData\Roaming\McNeel\Rhinoceros\5.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib\rhinoscript\selection.py"
  line 32, in script

Appreciate if you can kindly advise why the rhinoscriptsyntax module functions differently in the Python Editor and GhPython component.

Source Script:

import rhinoscriptsyntax as rs

def displayobjectattributes(object_id):
    source = "By Layer", "By Object", "By Parent"
    
    data = []
    data.append( "Object attributes for :"+str(object_id) )
    data.append( "Description: " + rs.ObjectDescription(object_id))
    data.append( "Layer: " + rs.ObjectLayer(object_id))
    #data.append( "LineType: " + rs.ObjectLineType(object_id))
    #data.append( "LineTypeSource: " + rs.ObjectLineTypeSource(object_id))
    data.append( "MaterialSource: " + str(rs.ObjectMaterialSource(object_id)))
    
    name = rs.ObjectName(object_id)
    if not name: data.append("<Unnamed object>")
    else: data.append("Name: " + name)

    groups = rs.ObjectGroups(object_id)
    if groups:
        for i,group in enumerate(groups):
            data.append( "Group(%d): %s" % i+1, group )
    else:
        data.append("<Ungrouped object>")

    s = ""

    for line in data: s += line + "\n"
    
    rs.EditBox(s, "Object attributes", "RhinoPython")

if __name__=="__main__":
    id = rs.GetObject()
    displayobjectattributes(id)
