passport of nodejs throw pass is not defined （nodejs 0.12.7）

my app use passport for auth user, but it throw exception sometimes like this:

ReferenceError: pass is not defined at deserialized (node_modules/passport/lib/authenticator.js:345:7) at app/app.js:89:10

the app.js is:

    var app, bodyParser, config, cookies, cors, e, express, http, keys, localStrategy, logger, multipart, passport, path, router, server, session, sessionStore, sessionUsed, session_store, util, uuid;  express = require('express');  http = require('http');  path = require('path');  session = require('express-session');  cors = require('cors');  session_store = require('sessionstore');  keys = require("keygrip")(['a', 'b']);  bodyParser = require('body-parser');  cookies = require('cookies').express;  passport = require('passport');  uuid = require('node-uuid');  multipart = require('connect-multiparty');  localStrategy = require('passport-local').Strategy;  config = require('./config/config');  util = require('./libs/util');  logger = require('./libs/logger');  sessionStore = session_store.createSessionStore(config.getMemCache());  sessionUsed = session({   secret: config.getCookieSecret(),   genid: function() {     return uuid.v4();   },   cookie: {},   saveUninitialized: true,   resave: true,   store: sessionStore });  app = express();  router = express.Router();  app.set('port', process.env.PORT || config.getServerPort());  app.set('views', __dirname + '/../app/public');  app.set('view engine', 'html');  app.use(sessionUsed);  app.use(cors());  app.use(bodyParser.json());  app.use(bodyParser.urlencoded({   extended: true }));  app.use(multipart({   maxFilesSize: 2 * 1024 * 1024 }));  app.use(express["static"](path.join(__dirname, '/../app/public')));  app.use(cookies(keys));  app.use(passport.initialize());  app.use(passport.session());  passport.use('local', new localStrategy({   passReqToCallback: true }, util.checkUserPassword));  passport.serializeUser(function(user, done) {   return done(null, user); });  passport.deserializeUser(function(user, done) {   return done(null, user); });  require('./routes/router')(app, router, passport);  server = http.createServer(app);  try {   server.listen(app.get('port'), function() {     return logger.info('Express is running at：' + app.get('port'));   }); } catch (_error) {   e = _error;   console.log(e); } 

I have view the code which throw exception, like this

First, your error is not shown in the screenshot. In the screenshot, you're showing line 282 from authenticator.js. Your error message shows where your problem actually is- line 345 in function deserialized.

The reason for this error is because your deserialized function in your app.js is not passing on a user object. Your deserialized function is a copy of your serialized function, and it should not be. Here is what the two should look like:

passport.serializeUser(function(user, done){     done(null, user.id); });  passport.deserializeUser(function(id, done){     User.findById(id, function(err, user){         done(err, user);     }) }); 

Of course, you can't use this deserialization function without changing your serialization function to store the user.id or some unique identifier instead of trying to store the whole user. I don't know what happens when you try serializing the whole user, but I'm confident it's what's causing your problems.

Hope that helps!
