Hey @kkbrat9, have you ran your custom action server using the below command:

rasa run actions

3

@JiteshGaikwad: ran action server using this command

python3 -m rasa_core_sdk.endpoint --actions actions

root@ip-172-31-31-102:~/iplbot/try_version# python3 -m rasa_core_sdk.endpoint --actions actions
2019-10-18 14:07:07 INFO     __main__  - Starting action endpoint server...
2019-10-18 14:07:07 INFO     rasa_core_sdk.executor  - Registered function for 'action_match_news'.
2019-10-18 14:07:07 INFO     __main__  - Action endpoint is up and running. on ('0.0.0.0', 5055)

I think so the issue exists in your custom actions, just check the error while your run the custom action server

I don’t see anything specific. Am i missing something ?

root@ip-172-31-31-102:~/iplbot/try_version# python3 -m rasa_core_sdk.endpoint --actions actions
2019-10-18 21:42:35 INFO     __main__  - Starting action endpoint server...

@JiteshGaikwad Any suggestion to move forward ?

I tried example as here Actions

  1. So, endpoints.yaml has following
action_endpoint:
  url: "http://localhost:5055/webhook"
  1. Running rasa run actions has following
rasa run actions
/usr/local/lib/python3.6/dist-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
  from ._conv import register_converters as _register_converters
2019-10-21 14:17:16 INFO     rasa_sdk.endpoint  - Starting action endpoint server...
2019-10-21 14:17:16 INFO     rasa_sdk.executor  - Registered function for 'action_hello_world'.
2019-10-21 14:17:16 INFO     rasa_sdk.endpoint  - Action endpoint is up and running on http ('0.0.0.0', 5055)
  1. Now how respond to hello world ?

BTW, modifiied action.py to look as below

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 []

I am able to get thing working. Thanks for the help @JiteshGaikwad
