Error whilst attempting the getting started app

I’ve created a github issue for this. Sorry if that should have been done here first.

I’m just starting to use crossbar for the first time and I’ve hit an error when attempting to follow the getting started guide.

I’ve cloned this repo and successfully started my router from within the getting started folder but, when I attempt to start the python publishing client, I get:

"ws://crossbar:8080/ws" "realm1"
