Hello,
I am trying to follow Streams • Akka Documentation and play-scala-sample in order to use ActorFlow (my particular use case is to have an actor interfacing with an internal system on a proprietary TCP protocol while providing a REST API).
It looks like akka-stream-typed is not included by default because I got:
object typed is not a member of package akka.stream
[error] import akka.stream.typed.scaladsl.ActorFlow
I looked at the jars I used and I think I should be on Akka version 2.6.17. But if I add
libraryDependencies += "com.typesafe.akka" %% "akka-stream-typed" % "2.6.17"
I got:
[error] ## Exception when compiling 83 sources to XXXXX\target\scala-2.13\classes
[error] java.lang.NullPointerException
[error] scala.reflect.internal.Types$TypeRef.computeHashCode(Types.scala:2416)
[error] scala.reflect.internal.Types$UniqueType.<init>(Types.scala:1084)
[error] scala.reflect.internal.Types$TypeRef.<init>(Types.scala:2359)
...
I tried version 2.5.32 and still got a similar NPE
I also noticed the documentation for Akka Typed Stream is not available in the current doc page?
i.e. link Streams • Akka Documentation is OK but https://doc.akka.io/docs/akka/current/typed/stream.html is not found.
Is there any specific requirements in order to use akka-stream-typed?
