Rasa-x model fails to build

Using rasa: 2.0.1 rasa-sdk: 2.0.0 rasa-x: 0.33.0rc1

and running on a kubernetes deployment from the easy install script.

When I try to build a model, I get this error in the logs.

Encountered an exception while training. Please check the logs of the rasa worker container for more information.
