[BUG] ORM serialization problem with table connection.

[Lydanne]

Desc

JSON that appears when I perform an associated query of user and role Stringify() problem.

Code

RoleEntity.ts

import { BackReference, entity, Index, MinLength, Unique } from "@deepkit/type";
import { Common } from "./CommonEntity";
import { User } from "./UserEntity";
import { UserJoinRole } from "./UserJoinRoleEntity";

@entity.name("role")
export class Role extends Common {
  name!: string & Unique & MinLength<1>;

  note: string = ""; // 备注

  actions: string[] = []; // 权限

  users?: User[] & BackReference<{ via: typeof UserJoinRole }>;

  constructor() {
    super();
  }
}

UserEntity.ts

import { BackReference, entity, MinLength, Unique } from "@deepkit/type";
import { Common } from "./CommonEntity";
import { Role } from "./RoleEntity";
import { UserJoinRole } from "./UserJoinRoleEntity";

@entity.name("user")
export class User extends Common {
  username!: string & Unique & MinLength<4>;
  password!: string & MinLength<4>;

  name!: string & Unique & MinLength<1>;

  roles?: Role[] & BackReference<{ via: typeof UserJoinRole }>;

  constructor() {
    super();
  }
}

UserJoinRoleEntity.ts

import { entity, Reference } from "@deepkit/type";
import { User } from "@app/orm/entities/UserEntity";
import { Common } from "./CommonEntity";
import { Role } from "./RoleEntity";

@entity.name("user_join_role")
export class UserJoinRole extends Common {
  constructor(public user: User & Reference, public role: Role & Reference) {
    super();
  }
}
