These empty error seems to occur when there is an exception on server side https://github.com/jupyter/nbgrader/blob/2ef4451572306b7a84605c18c4a459c24fe4eb31/nbgrader/server_extensions/formgrader/static/js/manage_assignments.js#L418

Can you look at the log on the server ?

There is no error logged on the server side around the time when this happened.
