nodeclipse auto-complete not working on installed packages (aws-sdk) // Tern.java?

[iamtennislover]

I have installed aws-sdk and create a nodejs eclipse project, but i can't seem to get auto-completion on available methods in the module

here is my setup

1. Eclipse IDE for JavaScript and Web Developers Version: Photon Release (4.8.0) Build id: 20180619-1200
2. eclipse plugin: nodeclipse 1.0.2
3. eclipse plugin: javascript development tools-2.1.1
4. nodejs 0.13.0
5. installed tern.js IDE from marketplace: https://github.com/angelozerr/tern.java/wiki/Tern-Eclipse-IDE

I noticed that it works for http standard library, but not for AWS in the following code (which builds and works fine) in the following two screen

/**
 * http://usejsdoc.org/
 */
var http = require('http');
var AWS = require('aws-sdk');
var s3 = new AWS.S3();
console.info(s3);

http auto complete working

aws auto complete not working (as I can't find S3 or STS

also i keep getting the following error in eclipse error window
