Javascript Question

returning data to a middleware from a promise

i am new to nodejs, this might seem pretty trivial but i am having trouble retrieving data from a function that returns a promise. The response from the middleware is sent back to the front end. Here is my code

// middleware
app.get('/player', function(req, res) {
//data i want to return

var getPlayerId = function(name) {
return start(name)

//getplayers function
var getPlayers = function(data) {
return data;

I'm i sending the data back the wrong way? The response i see at the front end is an object with prototype as the only property. I can print out the data in getPlayers() and i see it is working fine.
