Wyze Bulb Flashing Script

I have a script that is supposed to do a temporary scene.create to capture the current state of a light, then flash it red for 5 seconds, then return to how it was. When I run the script, it goes solid red (doesn’t flash) and then returns to a green color. Is this something wrong with my script or should I be looking at the custom Wyze Bulb integration?

alias: Flash Entry Light
  - service: scene.create
      scene_id: entry_before
      snapshot_entities: light.entry_lamp

      flash: short
      entity_id: light.entry_lamp
