Hi Benjamin @holyone2two, I have a very similar error. I am installing RASA-X on a VM on digitalocean (ubuntu 20.4). I used the new Rasa Ephemeral Installer (REI) to install RASA-X without any custom configuration. When training models I get the same NoneType object has not attribute version and KeyError: worker. I asked my question here: Rasa X Unauthorized when training model
Did you find any solution? I am stuck for now
