in nestjs how to get dto list that include file?

i want to get dtos that includes file in nestjs. but i can't find how i get this json array in nestjs.

ex) json array

[
  {brand : "A", file : file},
  {brand : "B", file : file}
]

dto:

export class fileDto {
  brand: string;
  file: File;
}

i saw similar question. File field is not being included in @Body decorator in NestJS

is there any way to get this array in nestjs ?
