Blueprint not showing in UI?

I added the following file:

/config/blueprints/automation/homeassistant/tradfri.yaml

With a blueprint as follows.
But the blueprint is never showing up under “blueprints” in HA. What could be the cause?

blueprint:
  name: deCONZ - Tradfri Shortcut Button
  description: 'Control anything using Tradfri Shortcut Button remote'
  domain: automation
  input:
    remote:
      name: Remote
      description: Tradfri Shortcut Button to use
      selector:
        device:
          integration: deconz
          manufacturer: IKEA of Sweden
          model: TRADFRI SHORTCUT Button
    button_short:
      name: Button short press
      description: Action to run on press button
      default: []
      selector:
        action: {}
    button_long:
      name: Button long press
      description: Action to run on hold button
      default: []
      selector:
        action: {}
    
mode: restart
max_exceeded: silent
trigger:
- platform: event
  event_type: deconz_event
  event_data:
    device_id: !input 'remote'
action:
- variables:
    event: '{{ trigger.event.data.event }}'
- choose:
  - conditions:
    - '{{ event == 1002 }}'
    sequence: !input 'button_short'
  - conditions:
    - '{{ event == 1003 }}'
    sequence: !input 'button_long'

Nevermind, I went to General > Reload Automations.
And but it under /config/blueprints/automation/custom/.

That worked.

I am having the same problem, I did what you did and it still didn’t work
