Error when trying to create condition

[chhhris]

I'm setting up a script automation to control a split a/c system in my bedroom. 
The code below works but I want one of the starters to be a condition, so essentially both starters have to be met to start the automation. 

metadata:
name: Bedroom Heater Control
description: Automates heating for the bedroom A/C when the temperature drops below a set threshold.
automations:
starters:
- type: device.state.OnOff
state: on
is: true
device: virtualSwitchLessThan60F - Bedroom
- type: device.state.TemperatureSetting
state: thermostatTemperatureAmbient
lessThanOrEqualTo: 68F
device: Temp and Humidity - Chris's Bedroom
actions:
- type: device.command.OnOff
on: true
devices: Bedroom A/C - Chris's Bedroom
- type: device.command.ThermostatSetMode
thermostatMode: heat
devices: Bedroom A/C - Chris's Bedroom
- type: device.command.ThermostatTemperatureSetpoint
thermostatTemperatureSetpoint: 75F
devices: Bedroom A/C - Chris's Bedroom
- type: home.command.Notification
title: Bedroom A/C State Change
body: The heat is ON!!

Adding either of the starters as a condition gives an error. [The value should be [Condition] but is [Array] instead.

condition:
- type: device.state.OnOff
state: on
is: true
device: virtualSwitchLessThan60F - Bedroom

ERROR: The value should be [Condition] but is [Array] instead.

It's the dash in front of the type in the condition. That indicates an array. Just drop it. Something like this:

metadata:
  name: Bedroom Heater Control
  description: Turn on bedroom heater when the temperature drops below a set threshold.
automations:
  - starters:
      - type: device.state.OnOff
        device: virtualSwitchLessThan60F - Bedroom
        state: on
        is: true
    condition:
      type: device.state.TemperatureSetting
      device: Temp and Humidity - Chris's Bedroom
      state: thermostatTemperatureAmbient
      lessThanOrEqualTo: 68F
    actions:
      - type: device.command.OnOff
        devices:
          - Bedroom A/C - Chris's Bedroom
        on: true
      - type: device.command.ThermostatSetMode
        devices:
          - Bedroom A/C - Chris's Bedroom
        thermostatMode: heat
      - type: device.command.ThermostatTemperatureSetpoint
        devices:
          - Bedroom A/C - Chris's Bedroom
        thermostatTemperatureSetpoint: 75F
      - type: home.command.Notification
        title: Bedroom A/C State Change
        body: The heat is
