Blueprint Automation gives 500 error when saving

I seem to be having an issue with my Blueprint where I get a “Response error: 500” error when saving the Automation:

I have similar things already working in Automations with Scripts, but I’m trying to make a Blueprint to reduce the amount of maintenance required to maintain a bunch of copy-cat Automations.

This is my Blueprint:

blueprint:
  name: Control Button & Motion Activated Lights
  description: >-
    Turns on lights with adaptive lighting during the day, but at night, it turns
    on a much dimmer version.

    Using a permanent trigger disables temporary lighting until definite trigger.

Separately, I’m trying to make it so the four triggers are optional. If I don’t add them, I don’t want them to be required because not every room is the same. Is that possible?

Perhaps a thumbs up to these would help…
