Question

My code is as follows

var express = require('express'),
    everyauth = require('everyauth'),
  util = require('util'),
  Promise = everyauth.Promise,
  users = require('./users');

everyauth.twitter
  .consumerKey('')
  .consumerSecret('')
  .findOrCreateUser(function(session, accessToken, accessTokenSecret, twitterUserData) {
    console.log('pre promise');
    var promise = new Promise();
   users.findOrCreateByTwitterData(twitterUserData, promise);
    return promise;
  })
  .redirectPath('/');

It prints ‘pre promise’and then crash is as follows

pre promise

/.../node_modules/everyauth/lib/modules/everymodule.js:348
  throw err;
        ^

Users looks like:

var cradle = require('cradle');
var c = new cradle.Connection('...', 80, {
    auth:{username:'admin', password:'...'}
});
var users = c.database('users');

module.exports.findOrCreateByTwitterData = function(twitterUserData, promise) {
    console.log('finding');
    users.view('docs/twitterId', {key:twitterUserData.id_str}, function (err, doc) {
        if (err) {
            console.log('twitter error');
            return;
        }
        if (doc) {
            promise.fulfill(doc);
        }
        else {
            var doc = {

            };
        }
        c.database('users').save(doc, function (err, res) {
            if (err) {
                console.log('error with users');
                return;
            }
            promise.fulfill(doc);
        });
    });
}

I have the same issue with everyauth 0.2.32.
Looks like everyauth.Promise is not being exported and the app crashes when you try to instantiate an ‘undefined’ class

You can check if (Promise == ‘undefined’)
