Null data returned from Firebase query

Database & APIs

I'm trying to show a simple list of data from Firebase and using the following tutorial on YouTube:
https://www.youtube.com/watch?v=VEro5T136SY&t=559s

I've looked everywhere I can think, documentation other YouTube vids but the whole integrating with Firebase just seems to run into a problem which even document or tutorial I try.

This tutorial is the latest I can find, so I assume it's up to date more or less with new changes in FF.

Everything seems fine, but when run in Test mode or even run on an emulator I see nothing. When in test mode, I seem to get an "error?" I think is causing it which says Lists<divisions>, can't be null. AFAIK I've followed the tutorial to the letter. Some screen shots will hopefully show what I've got.

Hoping someone can point me in the direction of what is wrong as I'm starting to pull my hair out.

TIA
