Rasa X currently only supports a SQLite tracker store with path 'tracker.db' when running locally. You can deploy Rasa X with Docker (https://rasa.com/docs/rasa-x/deploy/) if you want to use other tracker store configurations.
? Do you want to continue with the default SQLite tracker store?  Yes

Can you post the directory structure of your rasa project and the relevant custom code?

My project folder structure

> - bot
> -- actions
> -- data
> -- models
> -- custom
> --- channel
> ---- socketio.py

in my socketio.py file i have SocketIOInput class, I have copied the socketio.py file from rasa core/channels folder in to that custom folder

seems like your file isn’t named mysocket.py but rather socketio.py – I believe the path in your credentials should be custom.channel.socketio.SocketIOInput instead of custom.channel.mysocket.SocketIOInput

Sorry, i have changes the filename after few tries. The issue was solved. I used the socketio file of rasa 1.2x version but rasa-x version i used was lower than that. I think this was the problem.

Thanks @erohmensing, still I am learning.

No worries! Glad you figured it out!

Hi @erohmensing .

I have created custom channel in local environment its working fine(ubuntu, apache).

but in production mode(docker, nginx) my custom channel is not working, getting module not found error

  • my project installation path is /etc/rasa
  • custom connector file is located in: /etc/rasa/MyIo.py
  • I set pythonenv for custom connecter in Dockerfile

MyIo.py (4.9 KB) credentials.yml (55 Bytes) Dockerfile (766 Bytes)

My RASA_X_VERSION=0.29.1 RASA_VERSION=1.10.0

Please, can anyone help me to fix this issue?
