Whitesource.js not found

[punit9966]

when task is configured with latest node.js & npm, it throws below error,

Running "whitesource:web" (whitesource) task
module.js:544
    throw err;
    ^

Error: Cannot find module '/Users/xxx/MyProjects/projDirectory/node_modules/grunt-whitesource/node_modules/whitesource/bin/whitesource.js'
    at Function.Module._resolveFilename (module.js:542:15)

    at startup (bootstrap_node.js:191:16)
    at bootstrap_node.js:613:3
Error: Whitesource failed to run

This happens because execution script of the task is contains the absolute hard coded path for the dependent script and is not per latest node standards

node ./node_modules/grunt-whitesource/node_modules/whitesource/bin/whitesource.js run

this line should be modified and fixed to support newer versions of npm and node
