Post controller with File & Body

I'm using Nest framework and trying to make a Post request that gets a file and data here's what I did 

  @Post('upload')
  @UseInterceptors(FileInterceptor('file'))
  uploadFile(@Body('data') addRefundDto:AddRefundDto,@UploadedFile() file) {
    console.log(addRefundDto);
    console.log(addRefundDto.price);
    console.log(addRefundDto.refundType);
    return '   ';
  }

which prints :

{ "refundType":"test", "currency":"usd", "price":58.5, "flightId":4, "iAiCard":true }

undefined

undefined

It's like the dto gets the json as text (I also tried calling @Body()instead of @Body('data'))

I removed "Content-Type","application/json" from the request in PostMan so I can upload the file, is there anyway to solve this nicely ?

Thanks a lot !

You could always JSON.parse(addRefundDto) to put it back in JSON format. the body-parser package will only parse the data if you send it as application/x-www-form-urlencoded or application/json, otherwise you'll need to parse it yourself (in this case simply with JSON.parse()).

Maybe for someone the solution below will work.

You can use DTO without nested objects.

export class SomeDto {
    @ApiProperty()
    public readonly field1: string;

    @ApiProperty()
    public readonly field2: string;

    @ApiProperty({
        format: 'binary',
        type: 'string'
    })
    public readonly file: IMulterFile;
}
