如何用NestJS重新抛出HttpService调用错误？

import { Injectable, HttpService, HttpException, HttpStatus } from '@nestjs/common';

@Injectable()
export class MyService {
  constructor(private httpService: HttpService) {}

  async fetchData(): Promise<any> {
    try {
      const response = await this.httpService.get('https://api.example.com/data').toPromise();
      return response.data;
    } catch (error) {
      // 处理错误并重新抛出
      throw new HttpException('Failed to fetch data', HttpStatus.INTERNAL_SERVER_ERROR);
    }
  }
}
