Hi @LouisSpinelli,

I found this unanswered thread when doing a community cleanup.  Apologize for the issues you had with this assignment.  I believe this was related to a bug around the timeframe of your post last year that has since been fixed.  I know students at the institution I work for were also running into that exact error message for a few weeks.  As far as I know, Instructure does have the issue resolved now at least.  If you are still running into the problem, please let us know!
