Run button not working in Grading Admin tab

Describe the bug
This is a new bug I've run into in the past day or two. When I am in the Grading tab and press the Run button on a coding example, nothing happens. An error (below) appears in the Javascript console.

To Reproduce
Steps to reproduce the behavior:

1. Go to the Grading tab in the Faculty view.
2. Select "Assignment" from the first pulldown menu, and choose an assignment.
3. Select "question" from the second pulldown menu, and choose a question.
4. Select "student" from the third pulldown menu, and choose a student.

Expected behavior
The code should run.

Desktop (please complete the following information):

• OS: MacOSX 10.13

This isn't as general as I first presumed, but is affecting assignments I put together for sections 7.16 and 8.15, both involving Kiva data.
