How to fix H20 error when deploying app on Heroku? - node.js

Question

My app works fine locally and I have deployed before in the past with success, for some reason it is no longer working.
The build is successful but when I access the app it states there is an error and directs me to the error log.
UPDATE: The app has come online by itself and working. Just today I did another deploy and same thing with the logs.
I've got an updated log report which may help with identifying the issue below:
