okay, trying in @rilson17's SPOC I get:

Unable to deliver your submission to grader (Reason: unexpected HTTP status code [500]). Please try again later.

an edX problem?

I'm getting the same issue on the main MOOC too:

Unable to deliver your submission to grader (Reason: unexpected HTTP status code [500]). Please try again later.

edX made a change that fixed this after we escalated it
