创建父实体一对多关系时出错

Question

在保存关系方面遇到麻烦。我试图创建一个用户并传递电话号码数组（字符串类型）

按照我提供的方式，在中间件类型或参数phoneNumbers [0]中显示为字符串。这是我的实体的外观，

  @Description('A user has multiple phone numbers')
  @OneToMany(() => PhoneNumber, phoneNo => phoneNo.user, { nullable: true })
  phoneNumbers: PhoneNumber[] | string[];

  @Description('Ids of user\'s phone number')
  @RelationId((user: BaseUser) => user.phoneNumbers)
  phoneNumberIds: number[];

@Entity()
export class PhoneNumber extends BaseEntity {
  @Description('10 digit phone number of user')
  @Column('text')
  @Required()
  number: string;

  @Description('Weather this number is primary contact number of user or not')
  @Column('boolean')
  isPrimary: boolean;

  @Description('Many phone numbers are assosiated to a single user')
  @ManyToOne(() => BaseUser, user => user.phoneNumbers)
  user: BaseUser;

  @Description('Owner user\'s id')
  @RelationId((number: PhoneNumber) => number.user)
  userId: number; ```

Unable to identify the cause of facing this error
{ AJV_VALIDATION_ERROR: At BaseUser.phoneNumbers[0], value '090078602123' should be object...}
