python - Module Not Found Error in Rasa Custom Action Server using DOCKER

Question

I am new to Rasa and Docker. I am trying to build a chatbot using Rasa. I have included some custom actions in action.py file.

It works fine in my local, but on deploying in cloud (GCP), the custom actions don't get executed. I am using Docker to run the action server.

docker-compose.override.yml

version: "3.4"
services:
  rasa-production:
    volumes:
      - './custom_connectors:/app/custom_connectors'
  rasa-worker:
    volumes:
      - './custom_connectors:/app/custom_connectors'
  app:
    image: 'rasa/rasa-sdk:latest'
    volumes:
      - './actions:/app/actions'
    expose:
      - '5055'
    depends_on:
      - rasa-production

I am running the services using docker command

docker-compose up -d 

on checking the status of the docker containers, I see that the custom action server, keeps restarting. On checking the logs I get the below error:

021-01-25 07:52:32 INFO     rasa_sdk.endpoint  - Starting action endpoint server...

    from typing_extensions import TypedDict
ModuleNotFoundError: No module named 'typing_extensions'

I see that the typing_extensions module is installed in the python lib path.

Any help is appreciated.

Answer 1

I resolved the same issue by adding dependency 'typing_extensions'
