Express router multiple handlers issue - node.js

Question

I'm trying to set up Express routes bound with multiple controllers, of course they're supposed to receive functions, this is what I'm trying:
authRouter.get('/login/redirect/:provider', controllers.handleOAuth2Redirect, controllers.jwt);
This has sometimes worked, sometimes not, the only changes when works or not are minimal code changes, could be a require line, an expression, etc.
This is the error being thrown:
Error: Route.get() requires callback functions but got a [object Object]
So following code is the complete working controllers file:
'use strict';
var passport = require('passport');
var FacebookStrategy = require('passport-facebook').Strategy;
var TwitterStrategy = require('passport-twitter').Strategy;
var InstagramStrategy = require('passport-instagram').Strategy;
var OAuth2Strategy = require('passport-oauth2').Strategy;
var facebook_scope = ['email', 'user_about_me','user_friends','publish_actions'];
var passportFacebookOptions = {scope: facebook_scope};
passport.use(new FacebookStrategy({
clientID: process.env.FACEBOOK_FINALCUT_APP_ID,
clientSecret: process.env.FACEBOOK_FINALCUT_APP_SECRET,
callbackURL: 'http://localhost:9248/auth/login/redirect/fb'
},
function (accessToken, refreshToken, params, profile, done) {
return done(null, profile, params);
}));
passport.use(new InstagramStrategy({
clientID: process.env.INSTAGRAM_FINALCUT_CLIENT_ID,
clientSecret: process.env.INSTAGRAM_FINALCUT_CLIENT_SECRET,
callbackURL: 'http://localhost:9248/auth/login/redirect/ig'
},
function (accessToken,refreshToken,profile,done) {
return done(null, profile, {tokens: {accessToken: accessToken, refreshToken: refreshToken}});
}));
function oauth2ProviderLogin (request,response,next) {
var provider = request.query.provider;
switch (provider) {
case 'fb':
passport.authenticate('facebook')(request,response,next);
break;
case 'ig':
passport.authenticate('instagram')(request,response,next);
break;
}
}
function handleOAuth2Redirect (request,response,next) {
var provider = request.params.provider;
switch (provider) {
case 'fb':
passport.authenticate('facebook', {session:false})(request,response,next);
break;
case 'ig':
passport.authenticate('instagram', {session:false})(request,response,next);
break;
}
}
function jwt (request,response,next) {
var jwt = require('jsonwebtoken');
var token = jwt.sign({auth: request.authInfo}, '623145ca-7749-11e5-8bcf-feff819cdc9f');
return response.send({user: request.user, auth: token});
}
module.exports = (function() {
var authController = {
oauth2ProviderLogin: oauth2ProviderLogin,
handleOAuth2Redirect: handleOAuth2Redirect,
jwt: jwt
};
return authController;
})();
I've literally made it work by changing some lines of the controller functions. But the exports block has always remained the same. Naturally I nede to keep coding but then it stops working.
An example of something making it to stop working:
'use strict';
var passport = require('passport');
var jwt = require('jsonwebtoken'); // This makes it fail
var FacebookStrategy = require('passport-facebook').Strategy;
var TwitterStrategy = require('passport-twitter').Strategy;
var InstagramStrategy = require('passport-instagram').Strategy;
var OAuth2Strategy = require('passport-oauth2').Strategy;
That's it: adding a var jwt = require('jsonwebtoken') will make it fail.
Is there something I'm missing?

Answer 1

My error is actually silly:
Adding var jwt = require('jsonwebtoken') because I have a function with same name below:
function jwt (request,response,next) {
var token = jwt.sign({auth: request.authInfo}, '623145ca-7749-11e5-8bcf-feff819cdc9f');
return response.send({user: request.user, auth: token});
}
Just changing the name of any of those will fix the issue.
