LuboTerifaj opened a new issue, #1955: URL: https://github.com/apache/incubator-kie-kogito-examples/issues/1955
### Description Unable to run [Job Application Events Example](https://github.com/apache/incubator-kie-kogito-examples/tree/stable/serverless-workflow-examples/serverless-workflow-events-quarkus) properly. When you run your application, fill the Applicant data and submit it, nothing happens in the UI.
