Добавление нескольких активов в качестве владельцев в одной транзакции

Question

Я пытаюсь написать код, в котором я сначала делаю некоторые материалы, а затем эти материалы объединяются в модуль.Когда я выполняю транзакцию модуля, материалы должны быть частью транзакции.

Когда я пишу новый код, транзакция "internProducerModule" работает, но если я копирую его в новый файл, возникает ошибка:"TypeError: Невозможно установить свойство 'owner' из undefined"

Как я уже упоминал, если я копирую код, он не работает, но когда я удаляю в асинхронной функции InternProducerModule весь код (строки) с помощью "материал1, ..., материал4) в нем и напиши им новый, он работает.

Вот код: Файл модели:

namespace org.master

// BASE DEFINTIONS

abstract participant Business identified by businessId {
  o String businessId
}

participant MaterialSupplier extends Business {
  o String materialSupplierName
  o Double accountBalance
  // Alle vorhandenen Materialien anzeigen
}

concept MaterialDetails {
  --> MaterialSupplier make
  o String materialName
  o String materialColour optional
  o String batch
  o Double amount
}

concept MaterialTransferLogEntry {
  --> Business seller
  --> Business buyer
  --> Material material
  o DateTime arrivalDateTime
}

asset Material identified by materialId {
  --> Business owner
  o String materialId
  o MaterialDetails materialDetails
  o QualityControlMaterial [] qualityControlsMaterial optional
  o MaterialTransferLogEntry[] logEntries
}

transaction InternMaterialSupplier {
  --> MaterialSupplier seller
