Zwave.py error in manager callback

I’m getting this error spammed in my logs every minute:

Error in manager callbackTraceback (most recent call last):

This happened after a recent upgrade from one of the older versions (74 I think) to 82.1. All the zwave lights appear to work fine still. I looked for something with the “warm_white” property, but couldn’t find it… and I shouldn’t have anything that supports a property like that (no smart bulbs). Any ideas?
