Struggling with input select option

Evening all,

I have have an issue using an input select

I keep getting an error and I don’t know why. The code I am using is below. It seems very simple but I am doing something wrong.

  - entity: input_select.floorplan_floor
    object_id: Door_9
    type3d: gesture
      domain: input_select
      service: select_option
       entity: input_select.floorplan_floor
       option: TV

which gives me an

key not provided @ data ‘option’

If I change
service: select_option
service: select_first
it works fine. It must be something I have wrong after the service: line but i can’t see what.

Please Help.
