Event is None when using Compound Trigger to trigger Deployment

[thoec]

Bug summary

I want to use a compound event trigger to trigger a Deployment and passing along the triggering events. Triggering the Deployment works, but, I can not get it to work passing parameters with data from the events to the Triggered Deployment. See the compound trigger example here: https://docs.prefect.io/v3/automate/events/automations-triggers#define-triggers-in-prefect-yaml. When I reference {{ event }} I just get None. {{ event }} works fine for my other Deployments which are triggered by a single event. So, my Deployment is triggered. But with None as parameter instead of the actual events triggering the Deployment.
