Template Condition: Error from Test button, but not in Developer Tools/Template

Would love to understand what is going on. Anyone know?

This is my full automation:

- id: '1619471711923'
  alias: Turn Off Sprinkler
  description: Turns off sprinkler if rain is forecast or the day is set to off.
  trigger:
  - platform: time
    at: input_datetime.sprinkler_start_time
  condition:
  - condition: template
    value_template: "{{ (states('input_select.sprinkler_setting') == 'Auto' and\n\
      \     states('input_number.precipitation_forecast') | float(1) < states('input_number.precipitation_threshold')\
      \ | float(1) and\n   ((states('input_boolean.sprinkler_mon') == 'off'  and now().weekday()\
      \ == 0) or\n    (states('input_boolean.sprinkler_tue') == 'off'  and now().weekday()\
      \ == 1) or\n    (states('input_boolean.sprinkler_wed') == 'off'  and now().weekday()\
      \ == 2) or\n    (states('input_boolean.sprinkler_thu') == 'off'  and now().weekday()\
      \ == 3) or\n    (states('input_boolean.sprinkler_fri') == 'off'  and now().weekday()\
      \ == 4) or\n    (states('input_boolean.sprinkler_sat') == 'off'  and now().weekday()\
      \ == 5) or\n    (states('input_boolean.sprinkler_sun') == 'off'  and now().weekday()\
      \ == 6))) or\n     states('input_select.sprinkler_setting') == 'off' }}"
  action:
  - service: switch.turn_off
    target:
      entity_id: switch.sprinkler
    data: {}

I get an error in the UI when I press the Test button on the Condition.

In Developer Tools/Template it returns true or false.

There are open issues for templates and zones in the condition tester.
