WARNING: Line: 33: setImageURL() url parameter value (undefined) is not a string.
I have several students who are getting this warning- however, I completed this lesson and am not getting a warning. We cannot find their bug?
so… for diagnosing problems setImageUrl takes both an id that is an image element along with the url afterwords if you don’t have both or they are reversed it could lead to such issues, not only that but without a current example i cannot diagnose your problem further
due note that if you wish to bring up bugs or troubleshooting issues it’s best to use the the tag for it along with the template that will allow for easier solutions
I await your reply
