How do I figure out what is causing this error?

Error in logs (lots of them):

22-03-05 09:49:52 ERROR (MainThread) [asyncio] Task exception was never retrieved

AttributeError: 'NoneType' object has no attribute 'get'

I see scheduler, addon, watchdog and a TCP port so it must be one of these add-ons causing the issue:

My guess is Node Red because its logs do show some messages on a CRON I setup to re-authorize Alexa every 2 hours otherwise it stops working (no announcements work), but the Node Red addon logs do not appear to be errors, just a log of what it did.

Edit: Guess #2 - some bad template without a default?? (‘NoneType’ object has no attribute ‘get’)

I too have this. Did you ever find a solution?

Looks like the issue is related to the Terminal & SSH Add-on. Disabling the add-on on my instance has stopped the errors.
