sockjs-node: Error: A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin'

Hi

I’m running node-server in windows in my local computer. With sockjs-client 1.0.0-beta.12 (I use browserify for bundle the frontend), when I try to connect chrome gives me this error:

XMLHttpRequest cannot load http://localhost:12540/websocket/info?t=1429552020306. A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'null' is therefore not allowed access.

It’s my fault or is a error from the beta version?

client

Net.prototype.connect = function(url, port, prefix) { //url: 'localhost', port: 12540, prefix: '/websocket'
    var _this = this;

    return new Promise(function (resolve, reject) {

        _this.sock = new SockJS('http://' + url + ':' + port + prefix);

        _this.sock.onopen = resolve.bind(null, _this);
        _this.sock.onmessage = _this._message.bind(_this);
        _this.sock.onclose = _this._close.bind(_this);
    });
};

server

Net.prototype.start = function(port, prefix) { //port: 12540, prefix: '/websocket'
    this.sockjs = Sockjs.createServer({ sockjs_url: 'http://cdn.jsdelivr.net/sockjs/0.3.4/sockjs.min.js' });

    var server = http.createServer();
    this.sockjs.installHandlers(server, {prefix: prefix});
    server.listen(port, '0.0.0.0');
    return this;
};
