How to find what's generating errors in logs? Specifically helpers.template for "zwave_device" - Unable to find this mention in config

I’m getting this regular error in my logs and I can’t seem to figure out what’s causing it. I’ve searched my configuration files, but I’m not seeing anything listed as “zwave_device” so I don’t know where it’s coming from.

Any ideas or suggestions on how to find what’s causing this?

I was getting this error using the Inovelli switch blueprints for some automations. See here if you have those blueprints: ZWave-JS - Inovelli LZW31-SN Red-Series Dimmer - #25 by pfunky
