Hi,
I just tried it out and it worked for my side. Did you docker-compose down and up it again?
Can you also post the logs of the app
container here?
You can do this by using sudo docker logs <your foldername>_app_1
For mine, my folder name is rasa_x
, to get the logs: sudo docker logs rasa_x_app_1
Here are the logs which shows that the action server is running correctly
2021-05-12 01:52:35 INFO rasa_sdk.endpoint - Starting action endpoint server...
2021-05-12 01:52:35 INFO rasa_sdk.executor - Registered function for 'action_hello_world'.
2021-05-12 01:52:35 INFO rasa_sdk.endpoint - Action endpoint is up and running on http://0.0.0.0:5055
Hope it helps!
[Edit] I created a new thread just now http://forum.rasa.com/t/rasa-x-connecting-to-custom-action-server-using-docker-discussion-and-tutorial/43481 to guide new users to set up action server with RASA X and to gather some advice from the experts. Hope it helps!
