rest - Spring/Postman Content type 'application/octet-stream' not supported

I'm using Postman to send the following request: enter image description here

My controller looks like this:

@RestController
@RequestMapping(path = RestPath.CHALLENGE)
public class ChallengeController {

    private final ChallengeService<Challenge> service;

    @Autowired
    public ChallengeController(ChallengeService service) {
        this.service = service;
    }

    @ApiOperation(value = "Creates a new challenge in the system")
    @RequestMapping(method = RequestMethod.POST, consumes = {MediaType.MULTIPART_FORM_DATA_VALUE, MediaType.APPLICATION_OCTET_STREAM_VALUE},
        produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.CREATED)
    public ChallengeDto create(@ApiParam(value = "The details of the challenge to create") @RequestPart("challengeCreate") @Valid @NotNull @NotBlank ChallengeCreateDto challengeCreate,
                           @ApiParam(value = "The challenge file") @RequestPart("file") @Valid @NotNull @NotBlank MultipartFile file) {
        return service.create(challengeCreate, file);
    }
}

I already tried to change the "consumes" to delete the APPLICATION_OCTET_STREAM_VALUE to MULTIPART_FORM_DATA_VALUE and also tried to delete it, but none of these helped.

Please tell me if you need more information. Thanks.

@Rokin Answer is good but dont need to place json in file and upload. You can achieve by passing content type to json object as well. Postman support content type options while sending form-data. for further see the below image which is self descriptive.
