Unable to get property 'tcp' of undefined or null reference

[aashakabragithub]

I followed few prerequisites steps from https://github.com/SAP/node-hdb/wiki/Develop-Chrome-Apps-for-SAP-HANA and also followed Readme.md from https://github.com/SAP/node-hdb

I will list down the steps here -

1. npm install hdb
2. npm install browserify
3. npm install chrome-net
4. node ./node_modules/browserify/bin/cmd.js -r buffer -r ./node_modules/hdb/lib:hdb -o ./hdb.js
   Step 4 so that hdb.js is created in root directory where my main.js (that contains connection code and query) and index.html are present.

Now my index.html has below scripts -

<script src="hdb.js"></script> <script src="main.js"></script>

And my main.js has below code--

var hdb = require('hdb');
var client = hdb.createClient({
host: HOSTNAME,
port: PORT,
user: DBUSER,
password: DBPASSWORD
});
client.connect(function (err) {
if (err) {
return console.error('Error:', err);
}
console.log(client.readyState); // connected
});

In above code, createClient works fine but when client.connect is called I am getting "Unable to get property 'tcp' of undefined or null reference" error in console.

Now for above error, when I referred https://github.com/SAP/node-hdb/wiki/Develop-Chrome-Apps-for-SAP-HANA, I could see they added an entry for tcp in manifest.json. But I am not developing chrome extension.

Can you please help, what am I missing here?
