[ERROR] websockets.exceptions.InvalidURI: None isn't a valid URI: scheme isn't ws or wss

[Gamliel]

Hello @davidmezzetti Thanks for this repository, it would help me a lot in my research!

I got an error while trying to launch the wikitalk pipeline.

The command I'm running:

python -m txtchat.agent ./wikitalk.yml

(I have a local wikitalk.yml file because I changed the model from XL -> base for ram usage.)

And this is the results:

Thanks for giving it a try!

Did you set the ENV variables below and have a RocketChat instance up?

# Set to server URL, this is default when running local
export AGENT_URL=ws://localhost:3000/websocket
export AGENT_USERNAME=<Rocket Chat User>
export AGENT_PASSWORD=<Rocket Chat User Password>

# YAML is loaded from Hugging Face Hub, can also reference local path
python -m txtchat.agent wikitalk.yml
