After updating my rasa core from 0.10 to 0.11

In the custom action file I wrote dispatcher and tracker in run function as:

```
games_list = tracker.get_slot(games)
dispatcher.utter_message(response)

```

but It gives me error **AttributeError: ‘CollectingDispatcher’ object has no attribute ‘get\_slot’** during executing. How should I resolve this issue?
