Error: Expected "0" to be defined

Hi,

I am getting an error for the following code:

var express = require('express');
var requestProxy = require('express-request-proxy');
var memoryCache = require('memory-cache-stream');
var app = express();

app.get('/data/find', requestProxy({
    cache: memoryCache(),
    cacheMaxAge: 10,
    url: "http://dataservice:5001/getdata/find?query=*"
}));

app.listen(5000, function () {
    console.log('Listening: 5000');
});

And the error is:

Deps from my package.json

  "dependencies": {
    "winston": "^2.2.0",
    "express-request-proxy": "^2.0.0",
    "express": "^4.13.4",
    "memory-cache-stream": "^1.0.4"
  },

Any idea what I am missing?
