Ionic Window10 FileTransfer upload

I have Ionic app for iOS, Android, and Windows10. When I’m trying to upload image file on Windows 10 using FileTransfer I have an exception:
description: "Internal server error (500)."
name: “WinRTError”

Image exist, and I can display it using file URL. (ms-appdata:///local/file.JPG)
On Android and iOS app working correctly.

Is it possible to upload file on Windows 10 using FileTransfer and how to do it correctly?
