Passing an entity object to a script to access its attributes

Configuration
1

I want to pass an entity to a script which contains several attributes I configured in customize.yaml.
Here is an entry in customize.yaml for reference:

binary_sensor.back_porch_cam_motion:
  icon: mdi:motion_sensor
  switch_entity: switch.patio_light_1
  enable_entity: input_boolean.enabledrivewayfloodsonmotion
  timer_entity: timer.patiolight
  duration_entity: input_number.durationlightsmotiondetect

The Idea I have is to create one script which handles all all the exterior lights by passing the state object for the motion detect binary sensor to the script. This will allow a common code block to handle all exterior lights, and eliminate code repetition.

test_script:
  alias: Light motion script
  fields:
    arg_binary_sensor:
      description: "Binary sensor object with the required attributes"
      default: binary_sensor.onvif2mqtt/back-porch-cam/motion
  sequence:
    - condition: and
      conditions:
        - condition: state
          # entity_id: input_boolean.enabledrivewayfloodsonmotion
          entity_id: "{{ state_attr(arg_binary_sensor, 'enable_entity')}}" 
          state: "on"
        - condition: state
          entity_id: timer.patiolight
          state: idle
        - condition: state
          entity_id: switch.patio_light_1
          state: "off"
    - service: timer.start
      data:
        duration: "{{states('input_number.durationlightsmotiondetect')}}"
      target:
        entity_id: timer.patiolight
    - service: switch.turn_on
      data: {}
      target:
        entity_id: switch.patio_light_1
  mode: queued
  icon: mdi:lightbulb-auto
  max: 10

This line from above is throwing an error in Studio Code Server:

 entity_id: "{{ state_attr(arg_binary_sensor, 'enable_entity')}}"

The error is

String does not match the pattern of "^(?!.+)(?!)[\da-z]+(?<!).(?!)[\da-z_]+(?<!_)\s?(?:,\s?(?!.+)(?!)[\da-z]+(?<!).(?!)[\da-z_]+(…

How do you access the attributes from a state object passed in to a script?

A State Condition’s entity_id option doesn’t support templates.

Replace the State Condition with a Template Condition.

Example (in shorthand notation):

  sequence:
    - condition: and
      conditions:
        - "{{ is_state(state_attr(arg_binary_sensor, 'enable_entity'), 'on') }}"
        ... etc ...

That was the issue. Thanks for your help!
