Content-Type 'multipart/form-data; border=charset=UTF-8' не поддерживается] при использовании Multipartfile ⇐ JAVA

[Anonymous]

Я пытаюсь загрузить изображение пользователя с помощью процесса MultipartFile, но всегда получаю одно и то же сообщение об ошибке: «charset=UTF-8» не поддерживается... Я пробовал много аннотаций, таких как @PostMapping(path="/new ", Consumer={MediaType.APPLICATION_JSON_UTF8_VALUE}) и другие решения, которые я нашел здесь, в SOF, но ничего не работает!
Может быть в этом случае конфигурация Spring Security ошибочна (я предположим нет) ? ... Я запускаю базовый зеркальный проект без Spring Security, и он работает...
Я запускаю тесты с помощью Postman
Postman
Кажется, что весь запрос, сделанный с помощью Body/form-data, отклонен, но если я запущу его с помощью Body/raw/json (без файла), все пройдет отлично!
