I can confirm this, having the same issue, but in this case referencing another entity. This is the test I did (based on this example):

- select:
    - name: "Porch Camera Day-Night Mode"
      unique_id: porch_camera_day_night_mode
      state: "{{ state_attr('camera.buienradar', 'friendly_name') }}"
      options: "{{ ['off', 'on', 'auto'] }}"
      select_option:
        - action: tts.google_say
          data:
            cache: false
            entity_id: media_player.nestaudio
            message: Test

This results in an unknown state:
