No logs, logbook events or errors but folder_watcher not working

I have the following configuration and automation but not getting any notifications (service: notify.mobile works for other automations), can anybody provide any guidance please:

    - /tmp
    - /mnt/cameras
  # Customization file
  customize: !include customize.yaml
  auth_providers:
   - type: homeassistant
   - type: legacy_api_password

  customize_glob:
    "sensor.*_moisture":
      icon: mdi:water
    "sensor.*_light_intensity":
      icon: mdi:white-balance-sunny
# Show links to resources in log and frontend
# introduction:

google_assistant: !include google_assistant.yaml
cloud: !include cloud.yaml
plant: !include plants.yaml
auth:

folder_watcher: !include folder_watcher.yaml
# Enables the frontend
frontend:

This is my folder_watcher.yaml:

  patterns:
    - '*.mp4'

And the automation:

 alias: File
 trigger:
 - event_data:
     event_type: created
   event_type: folder_watcher
   platform: event
 condition: []
 action:
 - data:
     message: '{{ trigger.event.data.path }}'
   service: notify.mobile
