I'm seeing the similar issue.
No changes to models.
Only change is upgrading from 5.15.1 to 5.16.1.
Seems related to signals and messages as models without them appear to deploy OK.
Attaching a simple model that throws the error

Hi,

the problem is with


<eventBasedGateway id="eventGate"></eventBasedGateway>

Event based gateway is not supported in the org.activiti.image.impl.DefaultProcessDiagramCanvas#drawEventBasedGateway.

You can fix it easily and create pull request.

Regards
Martin

cool. Will do.
But this was working in 5.15.1. Curious what changed.
