You need both an implicit FlowMaterializer and an implicit
ExecutionContext in scope. I haven't followed the chain to check why those
are needed but basically I keep adding them (one or the other or both)
wherever I have compilation errors and it works. It should be something
related to marshalling, I'll leave the answer to the more expert guys
around here.
val route =
extractFlowMaterializer { implicit mat =>
implicit val ec = mat.executionContext
formFields('color, 'age.as[Int]) { (color, age) =>
complete(s"The color is '$color' and the age ten years ago was ${age - 10}")
}
}
