I’m trying a simple hello-world in custom action but the bot don’t reply.

this is my action.py file :

```python
from rasa_sdk.events import SlotSet
from rasa_sdk import Action

class ActionHelloWorld(Action):
    def name(self):
        return "action_hello_world"

    def run(self, dispatcher, tracker, domain):
        dispatcher.utter_message("Hello world !") # send the message back to the user
        return []

```

domain.yml :

```auto
actions:
- utter_greet
- utter_goodbye
- utter_searching
- action_hello_world

```

and stories.md :

```nohighlight
## greet + ask_qst
* greet
  - action_hello_world

```

and this is the debugging during shell command :

```nohighlight

Why the bot don’t show the dispatcher.utter\_message(“Hello world !”) message defined in the action.py ?

I’m running action server with Docker from rasa/rasa-sdk:latest. rasa version : Rasa 1.5.0a1
