add_object method missing

[ManuelTraub]

In main.py an add_object method for the controller seems to be missing:

the following code fixed it for me:

def add_object(self, *args, **kwargs):
object_id = self.get_unique_id()
object = self.get_add_object(
*args,
object_id = object_id,
**kwargs
)
self.communicate(object)
return object_id

My setup:
Ubuntu 18.04.5 LTS
Python 3.9.7

Output for (python main.py --out-dir data --config-file configuration_files.json --config-start 0 --config-end 1 --scene-type scene_1):
