The sample code
*object Main extends App {*
* implicit val system = ActorSystem("akka-http-core")*
* implicit val materializer = ActorMaterializer()*
* val uri =
Uri("http://maps.googleapis.com/maps/api/elevation/json?locations=27.988056,86.925278";)*
* Http().singleRequest(HttpRequest(uri = uri)) onComplete {*
* case Success(res) => {*
* res.entity.dataBytes.runFold("")((s, b) => s + b.utf8String)
onComplete {*
* case Success(s) => {*
* println(s)*
*system.shutdown()*
* }*
* case Failure(t) => {*
* println(t)*
*system.shutdown()*
* }*
* }*
* }*
* case Failure(bad) => {*
* println(bad)*
*system.shutdown()*
* }*
* }*
*}*
prints the response fine but consistently produces an error:
*{*
* "results" : [*
* {*
* "elevation" : 8815.7158203125,*
* "location" : {*
* "lat" : 27.988056,*
* "lng" : 86.92527800000001*
* },*
* "resolution" : 152.7032318115234*
* }*
* ],*
* "status" : "OK"*
*}*
*[ERROR] [09/09/2015 13:27:43.956]

[ActorSystem(akka-http-core)] Outgoing request stream error
(akka.stream.AbruptTerminationException)*
*[success] Total time: 5 s, completed Sep 9, 2015 1:27:43 PM*
When is the right time to call ActorSystem.shutdown() in order to terminate
without errors?
TIA,
Matthew
