"property 'defineCommand' of undefined" error is appearing on calling apis provided by webdriver-js-extender

[helloabhi-zz]

In the before annotation, I have written below code

var webdriver = require('selenium-webdriver');

    var extendedWebdriver = require('webdriver-js-extender').extend(webdriver);

    extendedWebdriver.setNetworkConnection(5);

Please see the error mentioned below

[helloabhi-zz]

Please look into the information provided

What are you passing to extend? edit: I missed this from the original post because the code formatting was off.

I believe extend should be passed instance of Webdriver, not the module exported by require('selenium-webdriver')

MacOS Sierra 10.12.4
