I am writing an API with Node and Express, and use MongoDB as the database.

It has worked for a long time now, but today when I wrote some changes to a model, the server won't start anymore. I originally thought that a recent code change caused it, but even if I stash my changes and reset to a working state, the error occurs.

This is the error:

TypeError: pool.getAll is not a function
    at MongoCR.auth (/location/of/project/node_modules/mongodb/node_modules/mongodb-core/lib/auth/mongocr.js:56:26)
    at Server.auth (/location/of/project/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:1019:40)

    at g (events.js:260:16)

If I comment out all database connections the app runs. I've tried changing database, but it does not work either. I found this and this question and answer, and double checked versions and that all db-calls have callback-methods. I've used the last argument as the callback for calls that affect one entry, and toArray(function(err, result){}) when there are multiple entries returned.

Mongo version is 2.6.3, and I use the Node-mongodb driver.

I connect with 

var mongo = require('mongodb').MongoClient;
var url = process.env.MONGODB || 'mongodb://localhost:27017/test';
var myCollection;
mongo.connect(url, function(err, db) {
    if(err) console.log(err);
    myCollection = db.collection('myCollection');
});

Then I have methods for e.g. find: 

myCollection.find({}).toArray(function(err, result){
    // work with result    
});

I'm lost - thanks in advance.

  • The code provided by you works perfectly here. – DevAlien Sep 19 '15 at 23:08
  • Same here, are you sure the connection is not failing? You are not returning after the error logging, so this line `myCollection = db.collection('myCollection');` are being executed regardless if there was a connection error or not. – victorkt Sep 19 '15 at 23:11
  • Apparently I've had at least three different database URL's wrong in a row over the course of three hours. I have no words. Thank you very much for your time! – Esso Sep 19 '15 at 23:12
