Answer 1

The npm module connect-mongo can't handle mongodb+srv:// connection strings. You'll have to use the older connection string types that start with mongodb:// .

If you are using MongoDB Atlas I recommend to go to connect on the cluster view, then connect your application and then select Node.js version 2.2.12, not 3.0 .

You probably also have to change the /test or /admin in your connection string to /TheNameOfYourDatabase with your database name there. (See radihuq's answer below)

Answer 2

@ConstJS answer worked for me. Expanding on it a little bit -

If you're using Postman and your error looks like this:

"errmsg": "not authorized on admin to execute command { insert: [..] }, $db: \\"admin\\" }"

Note this specific part:

$db: \\"admin\\"

You'll want to change that to your DB name so go to your URI and find

mongodb.net:27017/admin

and change admin to your database name

Answer 3

It appears you are trying to access MongoDB's admin database and insert something which is not allowed. I am assuming you are using a connection string like:

mongodb://mongodb0.example.com:27017/admin

Make sure you update the /admin piece to the database you want to connect to.

Answer 4

This error is specific to the fact that you are passing a url mongo-connect doesn't know how to handle. Instead of the URL, you can pass the mongoose.Connection object and use the mongooseConnection property in the MongoStore options object.

new mongoStore({
  mongooseConnection: mongoose.connection,
  autoReconnect: true 
})

In order for this to work, you'll need to establish a connection first and then pass the mongoose.connection object to your mongoStore class.

 mongoose.connect(secret.database, {useNewUrlParser:true}, function(err) {
    if(err) { 
      console.log(err)
    } else {
      app.use(session({
        resave :true,
        saveUninitialized:true,
        secret :secret.secretKey,
        store : new mongoStore({
          url:secret.database,
          autoReconnect:true })
      }));
      console.log('connexion OK');
    }
});

There are more elegant ways to handle it but that should get you started.
