Upload different fields through FileFieldsFastifyInterceptor, first one is only processed

[MuAladdinIbrahim]

Hello mate,
Thank you for those interceptors, you saved me time.

I face a problem using FileFieldsFastifyInterceptor which is the interceptor process only the first file in the form-data, all other fields are ignored. when I swap the fields in the request, the first one still be processed despite anything else.

  @UseInterceptors(
    FileFieldsFastifyInterceptor(
      [
        { name: 'logo', maxCount: 1 },
        { name: 'copy', maxCount: 1 },
      ],
      imageUploadOptions,
    ),
  )
  @Put('/:id/info')
  updateInfo(
    @Param('id') id: string,
    @Body() updateInfoDTO: UpdateInfoDTO,
    @UploadedFiles()
    { logo, copy },
  ) {
    console.log({ logo, copy }); // always one of them is undefined
    updateInfoDTO.logo = logo && logo[0]?.path;
    copy =
      commercialRegistrationCopy && copy[0]?.path;
    return this.service.updateInfo(id, updateInfoDTO);
  }

export const imageUploadOptions = {
  storage: diskStorage({
    destination: './uploads/images',
    filename: editFileName,
  }),
  limits: {
    fileSize: +process.env.maxAvatartFileSize || 3 * 1000 * 1000, /// 3mb,
  },
  fileFilter: imageFileFilter,
};

can you help?
