Sequelize Many to Many 关联时出错 - AggregateError

Question

我的应用程序中有以下模型设计：

@Table({ freezeTableName: true, tableName: 'Business', timestamps: true})
export class Business extends Model<Business> {

  @Unique(true)
  @Column(DataType.STRING(255))
  businessName: string;

  @Default(BusinessStatusEnum.pending_verify)
  @AllowNull(false)
  @Column(DataType.ENUM(BusinessStatusEnum.active, BusinessStatusEnum.canceled, BusinessStatusEnum.pending_payment, BusinessStatusEnum.pending_verify))
  businessStatus: string;

  @AllowNull(true)
  @Column(DataType.STRING)
  businessVerificationMessageId: string;

  @AllowNull(false)
  @Default(false)
  @Column(DataType.BOOLEAN)
  businessVerifiedEmail: boolean;

  // Many to Many association

  @BelongsToMany(() => SubscriptionPlan, () => BusinessSubscriptionPlan)
  subscriptionPlans: SubscriptionPlan[];

  @HasMany(() => BusinessSubscriptionPlan)
  businessSubscriptionPlans: BusinessSubscriptionPlan[];

}


@Table({ freezeTableName: true, tableName: 'SubscriptionPlan', timestamps: true})
export class SubscriptionPlan extends Model<SubscriptionPlan> {

  @AllowNull(false)
  @Unique(true)
  @Column(DataType.STRING(255))
  subscriptionPlanName: string;

  // Many to Many association

  @BelongsToMany(() => Business, () => BusinessSubscriptionPlan)
  businesses: Business[];

  @HasMany(() => BusinessSubscriptionPlan)
  businessSubscriptionPlans: BusinessSubscriptionPlan[];

}

@Table({ freezeTableName: true, tableName: 'BusinessSubscriptionPlan', timestamps: true})
export class BusinessSubscriptionPlan extends Model<BusinessSubscriptionPlan> {

  @PrimaryKey
  @AllowNull(false)
  @AutoIncrement
  @Column(DataType.INTEGER)
  id: number;

  @AllowNull(false)
  @Column(DataType.ENUM(BusinessSubscriptionPeriodEnum.monthly, BusinessSubscriptionPeriodEnum.annual))
  businessSubscriptionPeriod: string;

  @AllowNull(false)
  @Column(DataType.ENUM(BusinessSubscriptionPlanStatusEnum.active, BusinessSubscriptionPlanStatusEnum.upgraded, BusinessSubscriptionPlanStatusEnum.canceled))
  businessSubscriptionStatus: string;

  @ForeignKey(() => Business)
  @Column(DataType.INTEGER)
  businessId: number

  @BelongsTo(() => Business, 'businessId')
  business: Business;

  @ForeignKey(() => SubscriptionPlan)
  @Column(DataType.INTEGER)
  subscriptionPlanId: number

  @BelongsTo(() => SubscriptionPlan, 'subscriptionPlanId')
  subscriptionPlan: SubscriptionPlan;

  @HasMany(() => PaymentReceipt )
  paymentReceipts: PaymentReceipt[];

}

在我的代码中，我试图保存一个业务对象以及 Business 和 SubscriptionPlan 之间的关系表。

try {
                    business.isNewRecord = true;
                    const savedBusiness = await business.save();
                    await savedBusiness.reload();
                    if (subscriptionPlan && businessSubscriptionPlan) {
                        savedBusiness.addSubscriptionPlan(subscriptionPlan, { through: businessSubscriptionPlan });
                    }
                    return savedBusiness;
                } catch (error) {
                    throw new CustomError(messages[2].message.replace("${object}", "Business"), 500, error);
            }

我收到这个错误

(node:9252) UnhandledPromiseRejectionWarning: AggregateError at recursiveBulkCreate (/home/jose/Documents/prop-api/node_modules/sequelize/lib/model.js:2600:17) at processTicksAndRejections (internal/process/task_queues.js:93:5) ) 在 async Function.bulkCreate (/home/jose/Documents/prop-api/node_modules/sequelize/lib/model.js:2824:12) at async Promise.all (index 0) at async BelongsToMany.add (/home/ jose/Documents/prop-api/node_modules/sequelize/lib/associations/belongs-to-many.js:740:30)（使用node --trace-warnings ...显示警告的创建位置）<node_internals> /internal/process/warning.js:42 (node:9252) UnhandledPromiseRejectionWarning：未处理的承诺拒绝。 这个错误要么是因为在没有 catch 块的情况下抛出了异步函数，要么是因为拒绝了一个没有用 .catch() 处理过的承诺。 要在未处理的承诺拒绝时终止节点进程，请使用 CLI 标志--unhandled-rejections=strict （请参阅https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode ）。 (rejection id: 2) <node_internals>/internal/process/warning.js:42 (node:9252) [DEP0018] DeprecationWarning：不推荐使用未处理的承诺拒绝。 将来，未处理的承诺拒绝将使用非零退出代码终止 Node.js 进程。

我不知道我的模型是否有问题，或者是在保存业务的实际代码中，在我遵循此文档的模型中https://sequelize.org/master/manual/advanced-many-to-many .html我很感激你能给我的任何帮助。

我解决了这个问题，问题似乎出在这一行

@Table({ freezeTableName: true, tableName: 'BusinessSubscriptionPlan', timestamps: true})

我从直通表中删除了时间戳，并更改了保存业务的代码以传递文字对象而不是模型对象。

business.isNewRecord = true;
                    const savedBusiness = await business.save();
                    await savedBusiness.reload();
                    if (subscriptionPlan && businessSubscriptionPlan) {
                        savedBusiness.addSubscriptionPlan(subscriptionPlan, { through: {
                            businessSubscriptionPeriod: businessSubscriptionPlan.businessSubscriptionPeriod,
                            businessSubscriptionStatus: businessSubscriptionPlan.businessSubscriptionStatus
                        } });
                    }
