RuntimeError: this event loop is already running

@nik202 Thanks for the help, I think I misunderstood. I am using Rasa Open Source and terminal, but also using Rasa X in local mode. However the webpage is blank. I get the following error

AttributeError: 'Sanic' object has no attribute 'auth'
'Sanic' object has no attribute 'auth'

I checked this topic AttributeError: 'Sanic' object has no attribute 'auth'

But my Rasa versions are different. (Rasa Version : 2.8.7, Rasa SDK Version : 2.8.2, Rasa X Version : 0.42.3). Do you know how to solve this?
