Поток ввода файла конструктора (S3Blob) не определен

/ 14 февраля 2020

Я пытаюсь использовать тип S3Blob для отправки файла фотографии в корзину S3. Просто пытаюсь запустить мое приложение локально, и я получаю следующую ошибку компиляции в моей функции doCreateItem. 

Compilation error (In /app/controllers/Application.java around line 45)
    The file /app/controllers/Application.java could not be compiled. Error raised is : The constructor FileInputStream(S3Blob) is undefined

Я явно импортировал java .io.FileInputStream в приложении. java
