Update connect-mongo.js

if user not created an auth for database ( especially work on localhost ) mongodb returns an TTL error because of it couldn't write to database via ensureIndex(), console.log(err) help to us to see mongodb error. ;)

I'm starting to see this error randomly, and have to restart to clear it. I'm using mongolab as my mongodb provider, and nodemon to restart the app when I save files.

you need to add an auth user to your database.
use mongo shell

$ mongo

use yourdatabasename
db.addUser("root", "12345");

// AUTH TEST

db.auth("root","12345");
// 1

Question: I'm connecting via standard URI:

mongdob://[username]:[password]@[server]:[port]/[instance]

-- since I'm reading/writing to the sessions collection, doesn't that mean the username/password I'm using is already auth'd?

[FusionAge]

I did the db.auth() as you instructed just to be safe...but it still appeared. I tested this by re-saving a file (so that nodemon would detect the change & restart the service) -- still get the TTL error, whether I run it via nodemon or manually.

I think this was related to MongoLab, I've been beating up on this with my local mongodb install and I haven't seen the issue reoccur. Sorry for any false alarms, but if anyone searches and they're using MongoLab, that was my issue.

I don't use authentication and I'm seeing this error as well. I can trigger it reliably by trying to open the webpage very quickly after starting the server. If I wait two seconds before reloading the webpage everything works. The actual error is: no open connections at Db._executeQueryCommand (node_modules/connect-mongo/node_modules/mongodb/lib/mongodb/db.js:1705). I'm using connect-mongo version 0.3.2.

I am having this issue too. connect-mongo + mongolab

[skotchio]

+1 I have the same error connect-mongo + mongolab

[cryptoquick]

I'm also having this issue with MongoHQ & connect-mongo 0.3.2.

connect-mongo.js:137 -- throw new Error('Error setting TTL index on collection : ' + s

Here is the solution of the issue: http://stackoverflow.com/questions/15748644/nodejs-expressjs-passportjs-sessions-on-cloud9-connecting-to-appfog-mongo

[cryptoquick]

Ah yeah, I see what's happening-- at least, in my code. I'm feeding the wrong database object into my express session middleware. Thanks!

Solved by mongo-native-driver https://github.com/mongodb/node-mongodb-native/issues/966 @1.3.1

[acornejo]

+1 with latest version of mongodb driver and connect-mongo.

I've been having this exact same problem using MongoLab.

I've found a fix though!

I add a callback to my express.session method, and then the TTL error goes away! I take the callback out, and it comes back every time I make my first call after firing up my node app.

Perhaps this will resolve things for you too?

api.use(express.session({
  store: new MongoStore({
    url: config.mongo.url
  }, function () {
    console.log("db connection open");
  })
}));

Worked for me, thanks.

Still have this error when I tried to run a test with supertest.

I want to test a register process protected by csrf, here is the code:

var request = require('supertest');
var agent = request.agent(app);
var user = { email: 'test@gmail.com', password: 'dummy' };

agent
  .get('/signup')
  .end(function(err, res) {
    // Get hidden _csrf value
    var token = res.text.match(/_csrf.*?value=['"](.*?)['"]/)[1];
    user._csrf = token;
    agent.saveCookies(res);
    agent
      .post('/signup')
      .send(user)
      .end(done);

Any tips?

[igorauad]

vovan22, thanks for pointing this solution. This one worked for me.

[jtremback]

I used this to fix the problem, but now it is cropping up again when I try to run the app from my tests.

@jtremback this PR saved me.

That's really strange. I found the module connect-mongo-store does the same exact thing as this one, but works. I'll let you know if any problems come up with it as well.

EDIT: So, I was getting a completely different error with that other module, switched back to this one, and everything works fine. I should probably just learn how these work myself at this point.

@thepuzzlemaster solution worked for me.

Following is my code for express web server and mongoose connection:

var express = require('express');
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var expressSession = require('express-session');
var mongoStore = require('connect-mongo')({session:expressSession});
var mongoose = require('mongoose');

require('./models/users_model.js');

var conn = mongoose.connect("mongodb://localhost:/myapp");
var app = express();

app.set("view engine","html");
app.set('views','/views');
app.engine('.html', require('ejs').__express);

app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());
app.use(cookieParser());
app.use(expressSession({
secret: 'SECRET',
cookie: {maxAge: 60601000},
store: new mongoStore({
db: mongoose.connection.db,
collection: 'sessions',
})
}));
require('./routes')(app);

app.listen(9090);

When i run this file, i get the following error:
