Hi, I was testing custom slot mapping via custom action, but it seems it is providing errors as follows.

 ![image](https://europe1.discourse-cdn.com/flex013/uploads/rasa/original/3X/4/7/47c0cdf0e238145c329b1cd037abdda2e5722ce0.png)

  
Code:

```python

class ValidateTeamName(Action):
    def name(self) -> Text:
        return "action_extract_team_name"

    def run(
        self,
        dispatcher: "CollectingDispatcher",
        tracker: Tracker,
        domain: "DomainDict",
    ) -> List[Dict[Text, Any]]:
         return [SlotSet("team_name", "barcelona")]

```

Domain:

```nohighlight
slots:
  event_type_major:
    type: text
    influence_conversation: false
    mappings:
    - type: custom
      action: action_extract_team_name

actions:
- action_extract_team_name

```
