can not flash a light in color anymore

[wild isle]

      - action: light.turn_on
        data:
          flash: long
          brightness_pct: 100
          rgb_color: [255,100,100]
        target:
          entity_id: light.alarm

worked before, or even templated like this:

  lights_flash_on_color:
    sequence:
      - action: light.turn_on
        target:
          label_id: alarm_lamp
        data:
          flash: long
          color_name: >
            {{states('input_select.flash_color')|lower}}

however, I not notice this no longer sets the color. Ive check the actions page in dev tool, but this still reproduces this same syntax. Has something changed in the light integration, or maybe Hue? Ive tried on the above entity, which is a light group, but alos on a singel supporting Hue light..

this seems to work, splitting up the color setting first, and then flash that light lights_flash_on_color: sequence: - action: light.turn_on target: label_id: alarm_lamp data: color_name: > {{states('input_select.flash_color')|lower}} - action: light.turn_on target: label_id: alarm_lamp data: flash: long
