[Bug] 502 Bad Gateway when updating profile

When trying to add a profile picture, It fails and I get a red popup with no text in the bottom right. Looking in the console I see the error "502 bad gateway".

The image is a 100kb png file made with mac screenshot tool.

Proposed:
1. Updating a profile with a profile image should succeed.
2. If it doesn't succeed, an error message should display in the red popup box.
