Akka Typed Actors and AKka Http - cannot find ActorRefFactory

Question

I am trying to work with typed actors version 2.6.3 and akka http version 10.1.11 while all worked fine in non typed actors , now I am getting compilation error

object Main extends App {

   def createServer(implicit system: ActorSystem[IdentityCalculated]) = {

implicit val materializer = ActorMaterializer()

 }
 def apply(): Behavior[IdentityCalculated] = {
Behaviors.setup { context =>

  val identityManager = context.spawn(IdentityManager(), "identity-manager")

  implicit val timeout = Timeout(10, TimeUnit.SECONDS)
  implicit val scheduler = context.system.scheduler

  identityManager.tell(CalculateIdentity(context.self))

  Behaviors.receiveMessage{
    case IdentityCalculated(_,_,_) =>
      println("got response")
      Behaviors.same
  }
}

}
ActorSystem(Main(), "credentials-manager")

}

what am I missing? I want to create http server when I get the message that the identity was calculated how ever i am getting compilation error in the materializer creation

Main.scala:19:50: implicit ActorRefFactory required: if outside of an Actor you need an implicit ActorSystem, inside of an actor this should be the implicit ActorContext [error] implicit val materializer = ActorMaterializer() [error] ^ [error] one error found

thanks

If you hit a compilation error and want help about, indicating/pasting the trace is required. — cchantep

You can use classic streams (which are typed, despite running on an untyped ActorSystem) by replacing:

implicit val materializer = ActorMaterializer()

with

implicit val materializer = system.classicSystem
