Hi Sergey, The error coming up from the back end is MEDIA_UPLOAD_ERROR_CUSTOM_EXIT_NOT_ALLOWED which is because you are trying to write a custom exit for HTML5 bundles, which is not allowed. We're looking to update the error message so that you will see this error in the future rather than UNKNOWN.
