I also got this problem. Anyone can help?:joy:

You should be importing Action class like this in your actions.py:

from rasa_sdk import Action

Check if all your imports are correct or not. The error is showing up in your action server terminal output.

I imported some libs from rasa_sdk but still got the ‘custom action not found error’.

from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.forms import FormAction
from rasa_sdk.events import SlotSet, UserUtteranceReverted, ConversationPaused

The detailed errors look like as following.

I think I will need all the details. Can you ask another question in the forum with all the details and errors. That would make things clearer.

Thanks tonysinghmss. I have figured out this problem just now. I didn’t specify the actions.py file, so that the custom action server didn’t start the .py file.

7

hi @nicolasNi i get same error how did you specify the actions.py file?

8

The path of actions.py file is demo/actions.py

Then run the following command to run custom action with specified .py file.

rasa run actions --actions demo.actions

@nicolasNi i get this error

did you define action by using list ?

did you run action on your server ?

did check your endpoints.py file ?

did you debug your code as visual and run it rasa ?

Hi,

I ran your above command, but I still get the same error. Any other insights?
