Google Assistant fails to sync Alarm Control Panel with DETAILED_ACCURACY_RESULT_MISSING_FIELD when disarmed

[allenporter]

The problem

The steps are:

1. Add an alarm control panel entity to Home Assistant
2. Expose it into Google Assistant
3. Open the Google Home app

Expected: Alarm panel shows up
Actual: Alarm panel appears, but am unable to view or change its state, it just shows up as informational

There may be multiple things going on here:

• Below you see the error DETAILED_ACCURACY_RESULT_MISSING_FIELD and there is some discussion in https://issuetracker.google.com/issues/315337467 about how currentArmLevel needs to be supplied no matter what the armed state is. (It is omitted when disarmed as there is no disarmed armLevel)
• Even when armed, it still doesn't show up in Google Home. (Is this expected to work?)

What version of Home Assistant Core has the issue?

core-2024.4.3

Example YAML snippet

To configure an alarm panel:

alarm_control_panel:
  - platform: manual
    name: Home Alarm
    code: !secret alarm_code
    code_arm_required: false

Then configure Google Assistant:

google_assistant:
  project_id: woodgreen-277603
  service_account: !include service_account.json
  report_state: true
  expose_by_default: False
  secure_devices_pin: !secret alarm_code
  entity_config:
    alarm_control_panel.home_alarm:
      name: Home Alarm
      expose: true
      room: Front Door

Anything in the logs that might be useful for us?

When debugging is turned on I can see the device being written:
