Custom Action not returning

Rasa Open Source
1

Hello,

I am new to RASA.

When the intent that triggers my chat bots custom action the following error is returned.

“ERROR:rasa_core.processor:Encountered an exception while running action ‘action_show_time’. Bot will continue, but the actions events are lost. Make sure to fix the exception in your custom code.”

I have researched the issue and have seen this is a problem that affects many for various reasons. I have worked through the potential issues I have found and I am still confounded.

I am running via a jupyter notebook on Google Colab.

The Action Server is starting fine.

!nohup /usr/bin/python3 -m rasa_sdk.endpoint --actions actions --debug &

2022-03-08 21:03:38 INFO rasa_sdk.endpoint - Starting action endpoint server… 2022-03-08 21:03:38 INFO rasa_sdk.executor - Registered function for ‘action_show_time’. 2022-03-08 21:03:38 INFO rasa_sdk.endpoint - Action endpoint is up and running on http://0.0.0.0:5055 2022-03-08 21:03:38 DEBUG rasa_sdk.utils - Using the default number of Sanic workers (1)

My endpoint.yml follows:

This file contains the different endpoints your bot can use.

Server where the models are pulled from.

Model Storage

#models:

url: http://my-server.com/models/default_core@latest

wait_time_between_pulls: 10 # [optional](default: 100)

Server which runs your custom actions.

Custom Actions

#action_endpoint: url: “http://localhost:5055/webhook”

url: “http://0.0.0.0:5055/webhook”

Tracker store which is used to store the conversations.

By default the conversations are stored in memory.

Tracker Stores

#tracker_store:

type: redis

url: <host of the redis instance, e.g. localhost>

port: <port of your redis instance, usually 6379>

db: <number of your database within redis, e.g. 0>

password:

use_ssl: <whether or not the communication is encrypted, default false>

#tracker_store:

type: mongod

url: <url to your mongo instance, e.g. mongodb://localhost:27017>

db: <name of the db within your mongo instance, e.g. rasa>

username:

password:

I have referenced the endpoints in the agent.

agent = Agent.load(’./models/dialogue’, interpreter=model_directory, action_endpoint=’./endpoints.yml’)

My actions.py follows:

import datetime as dt 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_show_time"

def run(self, dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

dispatcher.utter_message(text=f"{dt.datetime.now()}")

     dispatcher.utter_message(text="Hello World!!")

    return []

My domain contains the action actions:

  • action_show_time
  • utter_happy
  • utter_greet
  • utter_menu
  • utter_destination_received
  • utter_enquiry
  • utter_toilet_location
  • utter_restaurant_enquiry
  • utter_goodbye
  • utter_thanks
  • utter_default

Thank you
