无法读取实现其他模型的Nest.js模型上未定义的属性

Question

最近，我开始在Nest.js上获得类型错误(我认为是在升级到v8之后)，并且无法解决它们。这是在模特身上。这是我的地盘模型。

import { Field, ObjectType } from '@nestjs/graphql'
import { Region } from '@biztobiz/api/region/data-access'
import { User } from '@biztobiz/api/user/data-access'

@ObjectType()
export class Territory {
  @Field()
  id: string

  @Field()
  createdAt: Date

  @Field()
  updatedAt: Date

  @Field({ nullable: true })
  name?: string

  @Field({ nullable: true })
  manager?: User

  @Field(() => [Region], { nullable: true })
  regions?: Region[]
}

这是我的用户模型。

import { Field, Int, ObjectType } from '@nestjs/graphql'
import { Role } from './role.enum'
import { UserStatus } from './user-status.enum'
import { Chapter } from '@biztobiz/api/chapter/data-access'
import { Company } from '@biztobiz/api/company/data-access'
import { Territory } from '@biztobiz/api/territory/data-access'
import { Region } from '@biztobiz/api/region/data-access'
import { Upload } from '@biztobiz/api/upload/data-access'

@ObjectType()
export class User {
  @Field({ nullable: true })
  id?: string

  @Field({ nullable: true })
  createdAt?: Date

  @Field({ nullable: true })
  updatedAt?: Date

  @Field({ nullable: true })

  @Field({ nullable: true })
  notifyBySMS?: boolean

  @Field({ nullable: true })

  @Field({ nullable: true })
  notifyByMobile?: boolean

  @Field(() => Chapter, { nullable: true })
  chapter?: Chapter

  @Field(() => [Company], { nullable: true })
  companies?: Company[]

  @Field(() => Territory, { nullable: true })
  territoryManaged?: Territory

  @Field(() => Region, { nullable: true })
  regionManaged?: Region

  @Field((type) => Int, { nullable: true })
  infusionsoftId?: number

  @Field({ nullable: true })
  password?: string

  @Field(() => Upload, { nullable: true })
  avatar?: Upload
}

这是我要犯的错误。

我已经翻阅了我所能找到的所有文档，并且看到了好几个人报告了这一点以及“修复”，但是没有一个对我有用。

这是一个循环依赖问题。您需要将其中一个模型关系移动到解析器中以修复此问题。
