Приведение в штучной упаковке

Question

Привет всем, у меня есть ошибка во время выполнения моего кода scala.он говорит java.lang.ClassCastException: scala.runtime.BoxedUnit не может быть приведен к scala.Tuple4

во время шага сохранения, когда я пытаюсь преобразовать наборы данных

val datasets = Try(Computing.process(input_bi.asInstanceOf[(Dataset[SortieFondsct], Dataset[SortieFondIP], Dataset[EntreeFondsct], Dataset[EntreeFondIP])], connector)) match {
      case Success(v) => System.out.println("Success")
      case Failure(err) => {
        val monitoringToSave = err match {
          case _: ArrayIndexOutOfBoundsException => Logger.error(ERROR_TYPE_MISSING_ARGS, "Computing", DRIVER_VIR_SORT_NAME, err, true, idDimTemps)
          case _: AnalysisException => Logger.error(ERROR_TYPE_INVALID_QUERY, "Computing", DRIVER_VIR_SORT_NAME, err, true, idDimTemps)

        }
        CassandraClient.saveMonitoring(monitoringToSave, connector)
        throw err
      }
    }
