NESTjs validate DTO after the request comes in

Question

Hihi, I have a special situation where I need to validate the body of the request but instead of failing I need to wrap that error array and send it as a response afterwards. With this I mean

  @Post('/archives')
  async bulkUpload(@Body() body, errors: []): Promise<ArchivesDto> {
    const archives = await this.service.save(body);
    return this.archivesMapping.getArchivesDto(archives, errors);
  }

async save(dto: ArchivesDto): Promise<any> {
   retrun ...resultof
}

and in the final response

{
archives:[] // the ones saved
errors: []// those who were bad
}

I mean, I can manually check each and everyone of them with joi or something like that and write a custom message, but the NestJS validation works well and I need to upgrade it a little bit
