Rest value_template giving warning about attribute being unsafe

I’m trying to use a rest binary sensor to pull data from Tautulli’s API to check for an update. However, I’m getting WARNING messages in my log saying

Template variable warning: access to attribute 'update' of 'dict' object is unsafe. when rendering '{{ value_json.response.data.update }}'

Is there a way to make this warning go away? Do I need to check that value_json.response.data isn’t null first?

Here is my rest component configuration

- platform: rest
  resource: https://tau.deadlypenguin.com/api/v2?apikey=XXXX&cmd=update_check
  value_template: "{{ value_json.response.data.update }}"
  device_class: update
  name: Tautulli Update Available

I’d also note that I have a similar one that goes through a different cmd but does not produce any warnings in the logs.
