can you just replace "Duration.Inf" with a shorter duration ? how about
import scala.concurrent.duration._
val timeout = new Timeout(10 seconds)
Await.result(result.future, timeout.duration)
or
val timeout = new FiniteDuration(10, TimeUnit.SECONDS)
Await.result(result.future, timeout)
or simply
import scala.concurrent.duration._
Await.result(result.future, 10 seconds)
