Comment 2 for bug 1456573

Sadly, but its a known issue. Some cosmetic surgery is possible at the moment by applying this patch: https://review.fuel-infra.org/#/c/6303/ (it turns 500 into 400 BadRequest), but, alas, it won't help uploading the image.

A different mechanism for large file upload has to be implemented, possibly based on keystone trusts (https://bugs.launchpad.net/fuel/6.0.x/+bug/1441156 - see Mike Fedosin's last comment on the subject).
