Next is not a function

[davich]

Strategy calls error here (passport-oauth2/lib/strategy.js:175). Error function (passport/lib/middleware/authenticate.js:361) expects there to be a next variable in scope. There is no next variable in scope.

At the least could you have a default callback that throws the error, so the error message doesn't get lost?
