Broken sensors (for Lovelace) from Rest API? How to fix?

Configuration
1

Hi,

FIX Edit: After once more carefully reading the documentation I noticed the state instead of value_template. The following worked and solved the issue

template:
  # Ducobox Sensors
  - sensor:
    - name: "Ducobox Status"
      state: "{{ state_attr('sensor.ducobox', 'state') }}"

Original issue below
Somehow this seems to stop working due to 2022.11, but I can’t find the reason nor a resolution.

I used to have the following setup to display a value from my REST API.

sensor:
- platform: rest
  name: duco_sensor_ducobox
  json_attributes:
   - state
   - trgt
   - actl
   - temp
   - rh
  value_template: 'OK'
  resource: https://myurl.test/nodeinfoget?node=1

- platform: template
  sensors:
    # Ducobox
    duco_ducobox_state:
      unique_id: duco_docubox_state
      friendly_name: "Ducobox State"
      value_template: '{{ states.sensor.duco_sensor_ducobox.attributes["state"] }}'

I have switched my REST, and I noticed that {{ states.sensor.ducobox.attributes.state }} isn’t recommended. I also noticed there is a new way in creating templates.

rest:
  # Ducobox
  - resource: https://myurl.test/nodeinfoget?node=1
    scan_interval: 5
    sensor:
      - name: "Ducobox"
        value_template: "OK"
        json_attributes:
          - "state"
          - "actl"
          - "trgt"
          - "temp"
          - "rh"

template:
  - sensor:
    - name: "Ducobox State"
      value_template: '{{ state_attr('sensor.ducobox','state') }}'

The individual sensor isn’t displaying anything, but the REST sensor is (saying “OK”), and all the attributes show the right information.Now I can’t figure out how to make “state” a separate sensor so I can add it to the Lovelace dashboard. I now with the “entity” card can do this, but I do not like the size of the card. I want to have a simple list like the “entities” card

What am I missing?
