Rasa X server: No registered action found

[Italosayan]

Hi there!

I followed the rasa master class tutorial to build my own rasa X server using google cloud. However, I have an issue when setting up the action server. The bot in rasa-x doesn’t reply when an action is triggered.

My current setup:

docker-compose.override.yml

version: '3.4'
services:
 app:
   restart: always
   build: .
   volumes:
   - './actions:/app/actions'
   expose:
   - '5055'
   depends_on:
   - rasa-production

The docker compose overwrite file builds from the following Dockerfile:

# Extend the official Rasa SDK image
FROM rasa/rasa-sdk:latest

# Change back to root user to install dependencies
USER root

# To install system dependencies
RUN apt-get update -qq && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

# To install packages from PyPI
RUN pip install --no-cache-dir pandas babel numpy

# Switch back to non-root to run code
USER 1001

My docker-compose ps output looks like this:

         Name                       Command                  State                                              Ports

I checked the output log of the rasa_app_1 service. The error is that no registered action found for name action_tell_conditions:

@Italosayan Hi, can you share the endpoints.yml file and domain.yml ?

@Italosayan

app

Change to:

action_endpoint:
  url: "http://app:5055/webhook"

and run the docker-compose

[Italosayan]

Still not working.

[Italosayan]

I rebuilt the images and now it works:

sudo docker rmi $(sudo docker images -a -q)
sudo docker-compose up -d

@Italosayan Nice. Did you updated the endpoints and re-build. Please close this thread for others. Good Luck!
