Why does everyauth crash with 'undefined is not a function'?

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;
        ^
TypeError: undefined is not a function

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);
        });
    });
}

in recent versions of everyauth you should use following syntax:

.findOrCreateUser(function(session, accessToken, accessTokenSecret, twitterUserData) {
    var promise = this.Promise();
    users.findOrCreateByTwitterData(twitterUserData, promise);
    return promise;
})

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')
