Node express issue, get the following "Cannot GET /test" in browser - node.js

Question

I have the following node express function:
var express = require('express');
var app = express();
// Listen on port 8000, IP defaults to 127.0.0.1
var server = app.listen(8000, function() {
console.log("node express app started at http://localhost:8000");
});
app.get("/test",
function(error, request, response, next) {
request.set("Content-Type", "text/html; charset=UTF-8");
if (error) {
request.status(403);
return next();
}
var id = request.query.snuid;
var currency = request.query.currency;
var mac_address = request.query.mac_address;
var display_multiplier = request.query.display_multiplier;
//
request.status(200);
});
When I load up the browser and enter in the url:
http://localhost:8000/test?snuid=1234&currency=1000&mac_address=00-16-41-34-2C-A6&display_multiplier=1.0
Im not sure why I am getting this error!? Not sure, it should work based on the documentation and examples I have seen. Any help would be appreciated.

I think is because you want to use a middleware and not a route, so maybe your code can be write in this way:
var express = require('express');
var app = express();
app.use(function(err, request, response, next) {
if (error) {
request.status(403);
return next();
}
});
app.get("/test", function(request, response, next) {
response.set("Content-Type", "text/html; charset=UTF-8");
var id = request.query.snuid;
var currency = request.query.currency;
var mac_address = request.query.mac_address;
var display_multiplier = request.query.display_multiplier;
//
response.status(200).end();
});
// Listen on port 8000, IP defaults to 127.0.0.1
var server = app.listen(8000, function() {
console.log("node express app started at http://localhost:8000");
});`
