wdcss-assert | Assertion always passing in webdriverIO v4+

[SimitTomar]

I am using V4.0.7 of webdriverIO along with version 2.0.0-beta-rc1 and my assertShots function is always passing even if the Actual Screenshot is different then the Expected Screenshot.

Here is my code:

var webdrivercss = require("webdrivercss");
var assertShots = require("wdcss-assert");

webdrivercss.init(this.client);

    var browsername = 'firefox';
    var pageIdentifier = PageName;

    return this.client
        .pause(10000)
        .webdrivercss(browsername,{
            name: 'UnderstandYourNeeds_Page'
        }, assertShots);

I think this is an issue with how wdio 4.0+ runs. Haven't had a chance to investigate.
