C2_W3 Programming Assignment Grading issue for Exercise 7

I am getting this above error after the submission. How do I resolve this?

Please expand or scroll the grader’s feedback box, so that it shows the rest of the error message (the “Details:” portion).

There is no mentioned other than that message.


I think you’ll have to wait for a mentor for that course to reply. I don’t have access to the materials for that course.
