Hi, which Rasa Core version did you use and how did you set the environment variable?

Example 4 should normally work.

3

Rasa 0.11.12

4

Then it cannot work. This feature was added in version 0.12, see rasa_core/CHANGELOG.rst at master · RasaHQ/rasa_core · GitHub .

I’m getting the same error in the latest rasa image “rasa/rasa:latest-full”

My endpoints.yml file contains:

action_endpoint:
  url: "http://${ACTION_SERVER}:${ACTION_PORT}/webhook"

My docker-compose defines the 2 environment variables:

  rasa:
    image: rasa/rasa:latest-full
    ports:
      - '5005:5005'
    environment:
      - ACTION_SERVER=action-server
      - ACTION_PORT=5055
    volumes:
      - ./rasa-bot/:/app
    command: ["run", "--enable-api"]

But when I ask the chatbot to do something requiring the action server, I get this error:

2019-11-13 06:13:22 ERROR rasa.core.actions.action - Failed to run custom action ‘action_create_doc’. Action server responded with a non 200 status code of None. Make sure your action server properly runs actions and returns a 200 once the action is executed. Error: http://${ACTION_SERVER}:${ACTION_PORT}/webhook

`

Shouldn’t this config in endpoints replace ${ACTION_SERVER} with the value in the environment variable ACTION_SERVER ?

When I put the below into my endpoints.yml, it works fine…

action_endpoint:
  url: "http://action-server:5055/webhook"

Thank you, Jason
