HarmonyOS 鸿蒙Next JSON.stringify序列化又出问题了？大佬帮忙看看 问题描述： JSON.stringify序列化隔段时间就会出现字段名称被修改的情况。请看图

附上代码：

@Observed
export class ProductDto{
  product:Product;//商品主信息
  inventoryBalanceList:InventoryBalance[];//库存余额集合
  customerQuotationDetailList:CustomerQuotationDetail[];//客户报价明细集合
  supplierQuotationDetailList:SupplierQuotationDetail[];//供应商报价明细集合
  barCodeList:Array<BarCode>;//条形码集合
  attachmentList:Array<Attachment>;//附件集合
  billDetailList:BillDetail[];//业务单据明细集合
  productInitDataList:ProductInitData[];//商品期初
  inventoryTransferDetailList:InventoryTransferDetail[];//库存调拨明细集合
