Multipart Exception, Java, SpringMVC, springframework.web.multipart.MultipartException: Failed to parse multipart servlet request;

Автор вопроса: Rom

Пишу импортер данных из csv файла в бд, имею вот такой метод контроллёра

@PostMapping(value = "/createTable", consumes = MULTIPART_FORM_DATA_VALUE)
public ResponseEntity importCsvData(@RequestParam("file") MultipartFile file) throws Exception {

    userService.parse(file.getInputStream());
    return ok().build();

И вот такой метод сервиса 

@Override
public void parse(InputStream reader) {
    CSVReader csvReader = new CSVReader(new InputStreamReader(reader));
    String[] record;

    try {
        while ((record = csvReader.readNext()) != null){
            User user = new User();
            if (record[0].equals("ssoid"))
                continue;
            user.setSsoid(record[0]);
            user.setTs(Integer.parseInt(record[1]));
            user.setGrp(record[2]);
            user.setType(record[3]);
            user.setSubtype(record[4]);
            user.setUrl(record[5]);
            user.setOrgid(record[6]);
            user.setFormid(record[7]);
            user.setCode(record[8]);
            user.setLtpa(record[9]);
            user.setSudirresponse(record[10]);
            user.setYmdh(record[11]);
            userRepository.save(user);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
