Rasa 2.2 Action server: ERROR rasa_sdk.executor - Failed to register package 'actions'

Rasa Open Source

Yes, I have looked all similar cases here in forum and also network search but still not working.

I followed this instructions
https://rasa.com/docs/rasa/how-to-deploy#building-an-action-server-image

Here is my Docker file

# Extend the official Rasa SDK image
FROM rasa/rasa-sdk:2.2.0
#COPY * /app/

# Use subdirectory as working directory
WORKDIR /app

# Copy any additional custom requirements, if necessary (uncomment next line)
# COPY actions/requirements-actions.txt ./

# Change back to root user to install dependencies
USER root

# Install extra requirements for actions code, if necessary (uncomment next line)
# RUN pip install -r requirements-actions.txt

# Copy actions folder to working directory
COPY ./actions /app/actions

# By best practices, don't run the code with root user
USER 1003

Command I give create docker image

docker build . -t rasa-sdk:2.2.0

No errors

but when I try start my action server with this command

docker run -v $(pwd)/actions:/app/actions --net action-link --name action-server-prod rasa/rasa-sdk:2.2.0

I get this error

Updated information

  1. I installed rasa-sdk:2.2.0 in my Ubuntu sandbox (Virtualbox) and FIRST time it installed BUT not SECOND time, same error as here
  2. Then I tried rasa-sdk:2.6.0 and that installed correctly, no errors. Tiried second time and also Ok

So something wrong in 2.2.0?! I use Rasa 2.2.0 because socketio is not working in higher versions.
