Hi, I’ve got the sample code setup with the default “ActionHelloWorld” enabled. I’ve tried searching on here and I can’t seem to find a solution, even though other people have had this same issue. I’m using vscode with python 3.7.5 To run the action server I’m running rasa run actions To run rasa i’m using rasa shell The rasa actions server is receiving and registering the function, but the “Hello World!” response is not being returned. When I used postman to send my own post command to the server, it is returning “Hello World!” under the image tag. The action endpoint is enabled as: action_endpoint: url: “ http://localhost:5055/webhook ” nlu.md ## intent:hello_world - hello world stories.md ## hello world * hello_world - action_hello_world domain.yml intents: - hello_world actions: - action_hello_world from typing import Any, Text, Dict, List from rasa_sdk import Action, Tracker from rasa_sdk.executor import CollectingDispatcher class ActionHelloWorld(Action): def name(self) -> Text: return "action_hello_world" def run(self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> List[Dict[Text, Any]]: dispatcher.utter_message("Hello World!") return []

Hi @James , Can you try rasa run actions --actions actions command instead. I got the same issue back then.
