My data service is resulting in a Java error when call the GET for a specific instance: http://localhost:8080/rest/customers/1

Any idea what the problem could be?

Here's the corresponding log entry:

Message: Failed to serve GET customers/1: Exception occurred in action '{}', all database changes executed by this action were rolled back

Problem solved. I hadn't defined the On Publish Microflow. Now it works.
