'use strict' and const keywork in the same file

I'm using node.js twitter-node-client module which uses qs (https://www.npmjs.com/package/qs)

Now I'm getting errors for any of my app calls with error mesage provided below

[SyntaxError: /usr/local/lib/node_modules/socialedge-twitter/node_modules/twitter-node-client/node_modules/qs/lib/index.js:5
const Stringify = require('./stringify');
^^^^^
Use of const in strict mode.]

As I know const (the same as let etc) are part of ECMAScript Harmony spec and I have to launch node with option --harmony as described here: http://stackoverflow.com/questions/22603078/syntaxerror-use-of-const-in-strict-mode

Unfortunately, I haven't access to the Node.js runtime or target system CLI - it is AWS Lambda which doesn't have any abilities to change this behavior.

Sorry boring you, I had very old node version installed.
