Hi Folks,
I want to develop custom action to query back end data in JAVAbase so I downloaded the code from GitHub - rbajek/rasa-java-sdk: Java SDK for the development of custom actions for Rasa and developed a simple hello world action.
Started RASA core in local on port 5005 and the action server on port 5055 in local. Updated endpoints.yml file as below.
# This file contains the different endpoints your bot can use.
# Server where the models are pulled from.
# https://rasa.com/docs/rasa/user-guide/configuring-http-api/#fetching-models-from-a-server/
#models:
# url: http://my-server.com/models/default_core@latest
# wait_time_between_pulls: 10 # [optional](default: 100)
# Server which runs your custom actions.
# https://rasa.com/docs/rasa/core/actions/#custom-actions/
action_endpoint:
url: "http://localhost:5055/webhook"
# Tracker store which is used to store the conversations.
# By default the conversations are stored in memory.
# https://rasa.com/docs/rasa/api/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: <password used for authentication>
# 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: <username used for authentication>
# password: <password used for authentication>
# Event broker which all conversation events should be streamed to.
# https://rasa.com/docs/rasa/api/event-brokers/
#event_broker:
# url: localhost
# username: username
# password: password
# queue: queue
When I am trying to http://localhost:5005/webhooks/rest/webhook,getting below error in logs. Seems RASA core is not able to communicate with action server.
Failed to run custom action 'custom_reason'. Couldn't connect to the server at 'http://localhost:5055/webhook'. Is the server running? Error: Cannot connect to host localhost:5055 ssl:default [Cannot assign requested address]

http://localhost:5055/health and http://localhost:5055/ end points of action server are perfectly working fine.
Is there any configuration missing here ??
Have you tried contacting the author? Also, looks like the last update was done 12 months ago, and there were some changes to the sdk recently due to the
