NestJs and Mongodb Project: Big problem with [email protected]

I have a problem that really makes me go round in circles since. I try to set up a Nest & Mongo project base to save time for the dev on the mongo NestJs couple. The elements are as follows:

// Package.json

//user.controller.ts

@Controller('users')
export class UsersController {
  constructor(private usersService: UsersService) { }

  @UseGuards(JwtAuthGuard)
  @Get()
  async findAll(
    @Res() res: Response,
    @HeaderDto() headersDto: HeadersDto,
    @QueryDto() getAllFilter: FindAllQueryFilter,
  ): Promise<Response<User[]>> {
    const aggregationResult = await this.usersService.findAll(getAllFilter, headersDto);

    res.header('x-count', String(aggregationResult.count));

    return res.send(aggregationResult.results);
  }
....
 

//users.service.ts

@Injectable()
export class UsersService {
  constructor(@InjectModel(User.name) private userModel: Model<UserDocument>, private readonly tokensService: TokensService,) { }


  async findAll(
    getAllFilter?: FindAllQueryFilter,
    aggregationOptions?: AggregationOptions,
  ): Promise<AggregationResult<User>> {
    return await aggregateBuilder(this.userModel, getAllFilter, aggregationOptions);
  }

//HeaderDTO

import {
    Body,
    createParamDecorator,
    ExecutionContext,
    HttpException,
    HttpStatus,
    Query,
    ValidationPipe,
  } from '@nestjs/common';
import { plainToInstance } from 'class-transformer';
  import { validate, ValidationError } from 'class-validator';
 
  export const BodyDto = (): ParameterDecorator => Body(new ValidationPipe({ transform: true, whitelist: true }));
  export const QueryDto = (): ParameterDecorator => Query(new ValidationPipe({ transform: true, whitelist: true }));
  export const HeaderDto = createParamDecorator(async (value: any, ctx: ExecutionContext) => {
    // extract headers
    const headers = ctx.switchToHttp().getRequest().headers;

    // Convert headers to DTO object
    const dto = plainToInstance(value, headers);

    // Validate
    const errors: ValidationError[] = await validate(dto);
  
    if (errors.length > 0) {
      //Get the errors and push to custom array
      const validationErrors = errors.map((obj) => Object.values(obj.constraints));
      throw new HttpException(`Validation failed with following Errors: ${validationErrors}`, HttpStatus.BAD_REQUEST);
    }
  
    // return header dto object
    return dto;
  })

;

When I do a Get:id, I have no problem, but when it comes to a getAll, I have this problem:

Node.js v21.6.2

You have an idea, besides I reinstalled the packages
