node.js empty reply from the server

Question

I have developed an API using node.js. In my local system API is running at port 2100, and i used the following curl command

curl -i -H "Content-Type: application/json" -X GET http://localhost:2100/xx/yy/zzz

And i received the following response:

HTTP/1.1 401 Unauthorized X-Powered-By: Express Vary: Accept-Encoding WWW-Authenticate: Bearer realm="Users" Set-Cookie: connect.sid=s%3A-qD8JTJTLNTnbc0bv2YsTcd2.sfJK8%2FOFan26l8QhuS4oxyEvUtGvhztevEcWX51kceE; Path=/; HttpOnly Date: Wed, 06 May 2015 09:31:30 GMT Connection: keep-alive Transfer-Encoding: chunked

Because i am using authorization i received the above response.

But in my production system i used the same curl command but i am receiving

curl: (52) Empty reply from server

I dont know whats happening? I searched a lot but i cant find a solution. Please share your ideas.

EDIT:

MY API has crashed due to this error:

Exception: Error setting TTL index on collection : sessions",

MY code:

app.use(express.session({
            secret: 'MEAN',
            store: new mongoStore({
                url: config.dbmongo.db,//db
                collection: 'sessions'
            })
        }));

Can you please explain what i am doing wrong?

Answer 1

You should be start listening after the db is connected. It might possibly be the issue.

Answer from github

mongoose.connect.on('connected', function () {
   var server = app.listen(app.get('port')), function () { 
     debug('Express server listening on port %d in mode %s', server.address().port, app.get('env'));
  });
});
