I think you must have modified it, or you're not using the Duo flow provided, because we don't rely on the UsernamePasswordContext as the source of the username, so we don't have anything calling that method that it's complaining about.

usernamePasswordContext.getUsername())

If I had to guess I suppose I would guess you're using some other Duo implementation, in which case you should switch. The one you're using appears to assume use of the Password flow, so that isn't really going to work.
