Я создаю API для отдыха, используя Flask, Flask-Restfull, Flask-Uploads и Marshmallow. Я использую Postman для проверки. Когда я отправляю запрос почтальону, я получаю изображение: [Отсутствуют данные для обязательного поля.]. Проблема заключается в том, что request.files возвращает пустой ImmutableMultiDict([]). Здесь я отправляю код и изображения запроса почтальона.

This endpoint is used to upload an image file. It uses the
JWT to retrieve user information and save the image in the user's folder.
If a file with the same name exists in the user's folder, name conflicts
will be automatically resolved by appending a underscore and a smallest
unused integer. (eg. filename.png to filename_1.png).
