id's are returned as array of two instead of one numeric value

Bug Report

I have a basic setup with one single entity and I create a CRUD service/controller by just following the docs.

But every entity returned has its ID transformed to an array of two IDs:

{
    "id": [
        2,
        2
    ],
    "code": "OkWtWjq-",
    "name": "test",
    "userPnl": "xxxxxx",
    "data": {
        "test": "12341234",
        "test2": "987654"
    },
    "createdAt": "2022-11-02T07:16:45.803Z"
}

The same happens when I request a list of IDs and get a newly created entity in return for POST and PATCH.

And I see that SQL generated looks like this. For some reason, it lists "Analysis"."id" two times.

SELECT "Analysis"."id" AS "Analysis_id", "Analysis"."id" AS "Analysis_id", "Analysis"."code" AS "Analysis_code", "Analysis"."name" AS "Analysis_name", "Analysis"."userPnl" AS "Analysis_userPnl", "Analysis"."data" AS "Analysis_data", "Analysis"."createdAt" AS "Analysis_createdAt" FROM "ComGen2"."analysis" "Analysis" WHERE ("Analysis"."userPnl" = @0) -- PARAMETERS: ["xxxxxx"]

Here’s the entity:

import {
  BeforeInsert,
  Column,
  CreateDateColumn,
  Entity,
  PrimaryGeneratedColumn,
  Unique,
} from 'typeorm';
import { nanoid } from 'nanoid';
import { ApiProperty } from '@nestjs/swagger';

@Entity({
  name: 'analysis',
})
@Unique('unique_code', ['code'])
@Unique('unique_user_and_name', ['userPnl', 'name'])
export class Analysis {
  @ApiProperty()
  @PrimaryGeneratedColumn()
  id: number;

  @ApiProperty()
  @Column({
    name: 'code',
  })
  code: string;

  @ApiProperty()
  @Column()
  name: string;

  @ApiProperty()
  @Column()
  userPnl: string;

  @ApiProperty()
  @Column({
    type: 'simple-json',
  })
  data: JSON;

  @ApiProperty()
  @CreateDateColumn()
  createdAt: Date;

  @BeforeInsert()
  setCode() {
    if (!this.code) {
      this.code = nanoid(8);
    }
  }
}

Controller:

import { Controller, UseGuards } from '@nestjs/common';
import { ApiTags } from '@nestjs/swagger';
import { Crud, CrudAuth, CrudController } from '@nestjsx/crud';

import { AzureADBearerGuard } from '../../auth';

import { AnalysisService } from './analysis.service';
import {
  Analysis,
  CreateAnalysisDto,
  UpdateAnalysisDto,
  User,
} from '../../domain';

@Controller()
@UseGuards(AzureADBearerGuard)
@ApiTags('analysis')
@Crud({
  model: {
    type: Analysis,
  },
  dto: {
    create: CreateAnalysisDto,
    update: UpdateAnalysisDto,
  },
})
@CrudAuth({
  property: 'user',
  filter: (user: User) => ({
    userPnl: user.userPnl,
  }),
  persist: (user: User) => ({
    userPnl: user.userPnl,
  }),
})
export class AnalysisController implements CrudController<Analysis> {
  constructor(readonly service: AnalysisService) {}
}

And service:

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { TypeOrmCrudService } from '@nestjsx/crud-typeorm';

import { Analysis } from '../../domain';

@Injectable()
export class AnalysisService extends TypeOrmCrudService<Analysis> {
  constructor(@InjectRepository(Analysis) repo: Repository<Analysis>) {
    super(repo);
  }
}

These are the versions I’m using:

"@nestjs/core": "^9.1.6",
"@nestjs/typeorm": "^9.0.1",
"@nestjsx/crud": "^5.0.0-alpha.3",
"@nestjsx/crud-typeorm": "^5.0.0-alpha.3",
"mssql": "^7.3.0",
"class-transformer": "^0.5.1",
"class-validator": "^0.13.2",

I tried to use version ^4 but with the same result.

The schema generated by Swagger seems correct though.

@lhfioravanso It looks like the maintainer doesn’t really maintain this project, so I used a fork. There are several out there. Although several days ago he approved several PRs, that solved this problem among others. Unfortunately, it hasn’t been released to npm yet.

This is actually fixed in this PR #797
