http Exception filter 적용이 안됩니다.

import {
  ArgumentsHost,
  Catch,
  ExceptionFilter,
  HttpException,
} from '@nestjs/common';
import { Response } from 'express';

@Catch(HttpException)
export class HttpExceptionFilter implements ExceptionFilter {
  catch(exception: HttpException, host: ArgumentsHost) {
    console.log('exception', exception);
    const ctx = host.switchToHttp();
    const response = ctx.getResponse<Response>();
    const status = exception.getStatus();
    const err = exception.getResponse() as
      | string
      | { error: string; statusCode: number; message: string | string[] };
    console.log('err', err);
    if (typeof err !== 'string' && err.error === 'Bad Request') {
      return response.status(status).json({
        ok: false,
        statusCode: status,
        data: err.message,
      });
    }

    response.status(status).json({
      ok: false,
      statusCode: status,
      data: err,
    });
  }
}

위처럼 하고난뒤에
main.ts 파일에
app.useGlobalFilters(new HttpExceptionFilter());

추가했는데 위처럼 에러 포맷이 안나옵니다.
const foundUser = await this.dataSource.getRepository(UserEntity).findOne({ where: { id } });
if (!foundUser) { console.log('User not found'); throw new BadRequestException('User not found'); }
{

"response": {

"message": "User not found",

"error": "Bad Request",

"statusCode": 400

},

"status": 400,

"options": {},

"message": "User not found",

"name": "BadRequestException"

}
