Problem with Chapter 3: User-Facing Backend Ticket: User Preferences

There is something wrong with this lesson. The provided solution doesn’t work or match the text in the code and the error messages don’t make sense. Was there an update to the underlying code for the class I’m not aware of since the solution text says "updateResponse " and the text in Visual studio shows “updateResult”. I’ve never had the provided solution not work.

I’ve had the same issue as well.

Was there any update on this?
