Я пытаюсь отправить изображение, захваченное плагином Cordova - camera, с помощью пост-запроса.
Отправка на Django rest-framework.это выдает мне ошибку type is not file

HTML отлично работает, и когда я отправляю данные, я проверял свою вкладку network, и запрос находитсяпослал.
и вот ответ, который я получаю {"item_image_1":["The submitted data was not a file. Check the encoding type on the form."],"item_image_2":["The submitted data was not a file. Check the encoding type on the form."],"item_image_3":["The submitted data was not a file. Check the encoding type on the form."]}
