I experience lots of Errors of such kind:
akka://scamandrill/user/StreamSupervisor-3/flow-25-0-unknown-operation]
Error in stage [One2OneBidi]: Inner stream finished before inputs
completed. Outputs might have been truncated.
(akka.http.impl.util.One2OneBidiFlow$OutputTruncationException$
Where to look for causes ?
Code for http-client is rather simple,
def executeQuery[S](endpoint: String, reqBodyF: Future[RequestEntity])(
handler: (HttpResponse => Future[S])): Future[S] = {
def rh(tryHttpInt: (Try[HttpResponse], Int)): Future[S] = {
tryHttpInt._1 match {
case Success(rsp) => if(rsp.status.isSuccess()) handler(rsp)
else {
Unmarshal(rsp.entity).to[String].flatMap ( msg =>
Future.failed(new
UnsuccessfulResponseException(rsp.status.intValue(),
rsp.status.reason(), msg))
)
}
case Failure(e) => Future.failed(e)
}
}
reqBodyF.flatMap { reqBody =>
val request = HttpRequest(method = HttpMethods.POST, uri = Uri(
"/api/1.0" + endpoint), entity = reqBody)
val clientFlow = Http().cachedHostConnectionPoolHttps[Int](
"mandrillapp.com")
val futureResponse = Source.single(request -> 1).via(clientFlow).map[
Future[S]](rh).runWith(Sink.head)
futureResponse.flatMap{ f => f }
}
}
source code:

passed handlers are also simple, spray-json unmarshalling with
unmarshal[List[MSenderDataResponse]]
