Opower - Failed setup, will retry: 'NoneType' object is not subscriptable

[totallydifferent]

The problem

I am in Tulsa, OK and using Public Service Company of Oklahoma (PSO). This integration has been working well for me for a while. I had a short period of time where it wasn't accepting credentials, but that resolved itself. Now I am getting another error with the integration failing to load at all. I have restarted the HA server and disabled/enabled the integration with no luck.
