Action server not working - IndentationError: unexpected indent

Rasa Open Source
1

Hi All, I am trying to run an action server so at first, it’s working nice but the rasa server failed to print the dispatcher .utter_massage. After that when I tried to run the custom action server again by using the command- rasa run actions it’s not working. It’s showing an indentation error.

My action.py code:

from typing import Any, Text, Dict, List
 from rasa_sdk import Action, Tracker
 from rasa_sdk.executor import CollectingDispatcher

 class ActionSaveConversation(Action):
    def name(self) -> Text:
        return "action_save_conversation"

    def run(self, dispatcher: CollectingDispatcher,
             tracker: Tracker,
             domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
         print (tracker.events)
         dispatcher.utter_message(text="All Chats Saved")
         return []

PS C:\Rasa_Projects\web_chat_rasa> rasa run actions

IndentationError: unexpected indent

Please help me to solve the problem.

Look at your file:

from typing import Any, Text, Dict, List
 from rasa_sdk import Action, Tracker
 from rasa_sdk.executor import CollectingDispatcher

As you and your error say, there are indentation errors.

Be careful with spaces and indents in Python. It should be like that:

from typing import Any, Text, Dict, List
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher

Your whole file has wrong indents, not just that part.

I strongly suggest learning Python before jumping into Rasa. Good luck :slight_smile:

Thanks Chris for your suggestion. I have solved it.
