akka spray:java.lang.IllegalArgumentException:需求失败

我是akka spray的新手：）

我有一个路由器演员：

class ProjectResource extends HttpServiceActor with DefaultJsonFormats  {
  import spray.http.MediaTypes.`application/json`

  def receive = runRoute {
    pathPrefix("rest" / "1.2") {
      path("users" / Segment / "projects" / Segment / "auth_url") { 
        case (key, id) =>
          get {
            respondWithMediaType(`application/json`) {
              requestContext =>
                val responder = context actorOf Responder.props(sender(), requestContext)
                context actorOf GetTask.props(key, id, responder)
            }
          }
      }
    }
  }
}

和响应者：

class Responder(replyTo: ActorRef, ctx: RequestContext) extends Actor with DefaultJsonFormats {
  implicit val authFormat = jsonFormat2(AuthDTO)

  def receive = {
    case x: AuthDTO =>
      ctx.complete(200, x)
      context stop self
  }
}

当我试图

旋度-v

我得到了这个错误（在ctx.complete（200，x）字符串上…）：

我做错了什么？救命啊

我发现了这个问题——这是在case类中，如果其中一个字段为空，请添加您的注释作为答案，它帮助我找到了问题并解决了它；）
