After clicking on Submit button for the quiz the pop up message shows up saying "Try Again" with traceback even though using the solution code from the solution tab. Please see screenshot attached.

There's currently an issue with Quizzes that is being looked into. So this is most likely part of that I think. Will update when it's fixed.

This should be fixed now!
