hey, you need to pass a dict, not just a name, e.g.

web_app = get_web_app({'random': random_agent})

your error message indicates that you're trying to call get_web_app(agent) for an instance of MCTSAgent. and just to help you help yourself, something not being subscriptable means a Python object doesn't implement __getitem__ like e.g. dict does. once you know that you'll immediately know that you're not passing the right argument to bot_map[bot_name].

Hope this helps!
