ISSUE: Notifications not working after KeyMaster update - Error rendering data template

[Frazior]

After an update in May 3(so 0.91-0.94) notifications from a child lock automation (keymaster_back_door Lock Notifications) stopped working. When I run a trace on the automation I get the following:

Error: Error rendering data template: UndefinedError: 'dict object' has no attribute 'event'

service: script.keymaster_back_door_manual_notify
data_template:
  title: back_door
  message: >-
    {{ trigger.event.data.action_text }} {% if trigger.event.data.code_slot > 0
    %}({{ trigger.event.data.code_slot_name }}){% endif %}

I did google the error but and found info but am completely lost about what it means. Any help is greatly appreciated.

Environment:

• OS: HassOS
• Type of system that HA is running on: NUC
• Home Assistant version: [e.g. 0.105.5]
