Lab3b - Grading Error
Hello,
I am having an issue with Lab3b. When I run the grading console after finishing the lab I receive a message stating "Attempt to de-reference a null object." I have reviewed the whole lab, tried multiple web servers, and updated the grader but none seem to fix the issue. The other issue is that this lab is difficult to go back and scrap since it is intertwined with many things.
Any help is greatly appreciated!
