Honeywell Set Temperature - Error

I’m trying to write a script that will automatically change the temperature of the house based on other criteria. So far my script looks like this:

# Turn up Heat         
  heat_on:
    alias: Heat On
    sequence:
    - service: climate.set_temperature
      data:
        entity_id: climate.thermostat
        temperature: 68
        target_temp_low: 68
        target_temp_high: 78

This is not working at all. It pulls the following error:

Error doing job: Task exception was never retrieved
Traceback (most recent call last):

    if getattr(self._device, "hold_{}".format(mode)) is False:

I’m probably not setting this up correctly but going over the Honeywell component section and the Climate section I’m still at a loss. Any thoughts on the matter?
