HA Alert results in "Referenced devices are missing or not currently available" warning

Hi everyone,

I recently created this alert:

name: Sump Pump one is off
entity_id: switch.plug_wp03_relay
state: "off"
repeat:
  - 10
  - 20
  - 30
  - 60
can_acknowledge: True
skip_first: False
title: "Sump Pump Power Issue"
message: "The plug should not be off"
done_message: "The plug is now on"
notifiers:
  - critical

The alert is working great, but my logs are filling with this warning message:

Has anyone come across this in the past?
As soon as I comment out this alert, the warnings go away.

Dang it… I had a bad device reference in Node-Red.
