'Consumes' по умолчанию имеет значение 'application / octet-stream' в Spring Boot RequestMapping, значение null при установке

Я пытаюсь создать простой обработчик запросов Post в Spring Boot, который потребляет JSON. 

@RestController
@EnableWebMvc
public class WebFormController
{
    @RequestMapping(path="/process-contact-form", method = RequestMethod.POST)
    public ResponseEntity<String> processContact(@RequestBody Form form) throws Exception
    {
        System.out.println("TEST TEST: Ran");
        return  new ResponseEntity<String>("Thank you for contacting us, we'll respond soon.", HttpStatus.OK);
    }
}

По умолчанию я понимаю, что это будет потреблять application / json. Однако, когда я делаю запрос с помощью curl или Postman, я получаю этот ответ от Spring ... 

DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/octet-stream' not supported

А в Postman я получаю «415 Unsupported Media Type».

Если я явным образом определите свойство 'consumes' ... 

@RequestMapping(path="/process-contact-form", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE)

Spring Boot возвращает это ... 

DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type '' not supported

Я пробовал установить потребление на «application / json», x- www-form-urlencoded, а также обычный текст и отправка этих типов запросов от почтальона, но я получаю те же результаты.

Я построил это на aws -serverless- java -container https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot и запускаю его из локального интерфейса командной строки SAM.

EDIT

Я переключил ведение журнала на DEBUG, чтобы получить более подробную информацию ...
