Node.js-Nginx 502

Question

I'm getting a 502 error in my production environment, but not on my local install of my app, for a certain route. I've narrowed the problem down to the callback of the .aggregate() method that I'm querying the database with.

This is the callback:

    function(err,f){
        var f = f[0].forms;

        if(err) console.log(err);
        if (callback) {
            res.setHeader('Content-Type', 'text/javascript');
            res.send(callback + '(' + JSON.stringify(f) + ')');
        } else {
            res.end("Callback not set");
        }
    }

It works for my local install. I'm using this callback to send the object to another source using jsonp. Is there something I'm not doing correctly?

If you're logging an error, probably best to not continue to the next line of code.

if(err) {
  console.log(err);
  return done(err); //or send the error page, or do something other than continue on.
}

Can you see more contents of the error message?
