voiceXML in evolution.voxeo.com, getting strange error

Question

I am new in voiceXML and I am trying to use evolution.voxeo.com to run simple XML codes. According to their website, we can post the recorded audio in multi-part format. So here is my XML code, that runs fine without record element. But when I add the record element, I get error. The fact that I am getting error is strange because I am receiving the actual audio file in my computer.

Here is node.js/express.js/multer code that I am using to receive the recorded file

var express = require("express");
var bodyParser = require("body-parser");
var fs = require("fs");
var multer = require("multer");
var app = express();
app.set("view engine", "jade");
app.set("views", __dirname + "/views");
app.post("/", multer({
    dest: "./uploads/",
    rename: function (fieldname, filename) {
        return hashCode(filename);
    }
}));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: true
}));

app.get("/", function (req, res) {
    res.sendStatus(200);
});

app.post("/", function (req, res) {
    res.sendStatus(200);
});

app.listen(80, function(){
    console.log("listening ...");
});

function hashCode(str) {
    var hash = 0;
    if (str.length == 0) return hash;
    for (i = 0; i < str.length; i++) {
        char = str.charCodeAt(i);
        hash = ((hash << 5) - hash) + char;
        hash = hash & hash;
    }
    return hash >= 0 ? hash : -1 * hash;
}

Answer 1

The http response to the submit should be the next VoiceXML content to process. I didn't notice anything in your content that suggested a VoiceXML response and the error is about an inability to process the next document.
