SmallRye and Kafka: SSE events not received in browser.

[chainhead]

I am trying out a version of Quotes application where, the Kafka topic is populated by an upstream DSL application. Further, the messages are JSON objects. When I access the end-point in Postman, I see a message as Error: aborted although, I can see HTTP status code 200. I can confirm that, the application connects and subscribes to the Kafka topic successfully. Also, I can see data in the topic when I run kafkacat.

Can you please advise what am I missing?

This is my application.

@Path("/events")
public class ApplicationStreamer {

  @Channel("application-events")
  Multi<ApplicationEvent> applicationEvent;

  @GET
  @Produces(MediaType.SERVER_SENT_EVENTS)
  public Multi<ApplicationEvent> stream() {
    return applicationEvent;
  }
}

This is my model.

public class ApplicationEvent {

  public JsonObject applicationEvent;

  /**
   * Default constructor required for Jackson serializer
   */
  public ApplicationEvent() {

  }

  public ApplicationEvent(JsonObject me) {
    this.applicationEvent = me;
  }

  // @Override
  // public String toString() {
  //   return applicationEvent.encode();
  // }
}
