You’re attempting to send a function.
remote ! Identify <<< Identify here is wrong
Note that it is a case class, that takes a parameter:
final case class Identify(messageId: Any)
remote ! Identify(“hello”)
should work just fine.
Ahah, my assessment of my stupidity was spot on, thanks ;-)
I had also tried:
remote ! Identify(remote)
but that didn't work either, following your hint:
remote ! Identity(remote.toSerializationFormat)
also works. Is there a list anywhere of what Akka/Scala types have
default protobuf serializers?
On a related note, I enabled "akka.actor.serialize-creators" but that
triggered:
[WARN] [SECURITY][02/21/2018 18:01:29.021] [main]
[DisabledJavaSerializer(akka://RITA)] Outgoing message attempted to use
Java Serialization even though `akka.actor.allow-java-serialization =
off` was set! Message type was: [class java.lang.Class]
which isn't exactly helpful in identifying the error. I suspect it's
cause by the companion object Props creator pattern that's recommended
in the docs, e.g.
object Controller {
def props = Props(new Controller)
}
If I use the
system.actorOf(Props(classOf[MyActor], arg1, arg2))
alternative I get a slightly different error:
[WARN] [SECURITY][02/21/2018 18:16:18.205] [main]
[DisabledJavaSerializer(akka://RITA)] Outgoing message attempted to use Java
Serialization even though `akka.actor.allow-java-serialization = off` was set!
Message type was: [class akka.actor.ActorSelection$$anon$1]
Doesn't this mean that "akka.actor.serialize-creators" is pretty much
useless in practice?
