Default event name/type in server sent event is "message". I am trying to change the event name but it is not working. I am using Play 2.5 and akka streams.
(actorRef,sourcePublisher)= Source
.actorRef[T](10, OverflowStrategy.fail)
.toMat(Sink.asPublisher(true))(Keep.both)
.run()
backsource = Source.fromPublisher[T](sourcePublisher).named("test1")
Ok.chunked(backsource via EventSource.flow)
.as(ContentTypes.EVENT_STREAM)
But it is not changing the event name/type. It is still listening to message event rather than test1. Please suggest. Any help is appreciated.
