Adding new object fails

[tanmana5]

Hi,

I am experimenting with adding new objects following the code in 'demo/unity_demo.ipynb'.

When I try to add new objects with new ids, the script execution fails.

    comm.reset(scene_id) 
    # adding new object
    success, graph = comm.environment_graph()
    sofa = find_nodes(graph, class_name='sofa')[0]
    add_node(graph, {'class_name': 'wineglass', 
                   'category': 'Props', 
                   'id': 1000, 
                   'prefab_name': 'PRE_PRO_Wine_glass_01',
                   'properties': ['GRABBABLE', 'RECIPIENT', 'POURABLE', 'MOVABLE'],
                   'states': []})
    add_edge(graph, 1000, 'ON', sofa['id'])
    success, message = comm.expand_scene(graph)
    print('Expand scene: ', success, message)
    comm.add_character()
    script = ['<char0> [Walk] <wineglass> (1000)',
          '<char0> [Grab] <wineglass> (1000)']
    success, message = comm.render_script(script=script,
                                      processing_time_limit=60,
                                      find_solution=False,
                                      image_width=320,
                                      image_height=240,  
                                      skip_animation=True,
                                      recording=False,
                                      save_pose_data=False,
                                      file_name_prefix='w')
    print(success, message)

Output:

Expand scene:  True {}
False {'0': {'message': 'ScriptExcutor 0: PROCESS WALK: Can not select object: wineglass. REASON: Unknown\nEXECUTION_GENERAL: Script is impossible to execute\n\n'}}

What am I missing here?
