Unable to send PATCH Request

[sairam228]

When i send the patch request, it's throwing function not found exception.
http = new HttpClient("baseurl");
response = http.patch("service","body")
After adding the below code to http-client.js file in node module it's working
patch(url, body, headers) {
return this.send('PUT', url, body, headers);
}
We may need to add this code there. Let me know if i am missing anything. Thanks
