    function Chat1() {
        var initESW = function (gslbBaseURL) {
        embedded_svc.settings.displayHelpButton = true; //Or false
        embedded_svc.settings.language = ''; //For example, enter 'en' or 'en-US'
        embedded_svc.settings.enabledFeatures = ['LiveAgent'];
        embedded_svc.settings.entryFeature = 'LiveAgent';

You can get more information from here regarding what I am doing. In this link ulr not being used, using local file.

I want to know how to fix getSessionData requires two non-null arguments ? this is really painful error 😨.

This error we can see on this url

https://service.force.com/embeddedservice/5.0/frame/session.esw.min.js

Solution 1:^[1]

Salesforce attempts to parse the URL of your webview in order to extract a domain.
The domain is then passed to multiple function calls, including getSessionData.
You can open the non-minified https://service.force.com/embeddedservice/5.0/eswFrame.js file and notice this block:

window.location.search.replace(/([a-zA-Z0-9]+)=([\S]+)/g, function(match, key, value) {
  if(key === "parent") {
    // Only take the parts between the first instance of // and the / following it.
    this.parentOrigin = value;
  }
}.bind(this));

This function is unable to parse a domain from a local file loaded with file:///, which is what you do when you load the webview. Thus the errors.

The solution is to host a local server within your app or to store your webview script on a remote server so Salesforce can properly parse the domain from the webview url.

For instance, loading the following script using a http://localhost URL displays the chat agent properly on Chrome desktop:

<html>
<body>
<script type='text/javascript' src='https://service.force.com/embeddedservice/5.0/esw.min.js'></script>
<script type='text/javascript'>
    var initESW = function (gslbBaseURL) {
        embedded_svc.settings.displayHelpButton = true; //Or false
        embedded_svc.settings.language = 'en'; //For example, enter 'en' or 'en-US'
        embedded_svc.settings.enabledFeatures = ['LiveAgent'];
        embedded_svc.settings.entryFeature = 'LiveAgent';
        embedded_svc.init(
            'https://ulr.my.salesforce.com',
            'https://ulr.force.com/visualforce',
            gslbBaseURL,
            '00D7a00000055uj',
            'Products',
            {
                'baseLiveAgentContentURL': 'https://c.la3-c1cs-cdg.salesforceliveagent.com/content',
                'deploymentId': '720008Oqg',
                'buttonId': '5730PID',
                'baseLiveAgentURL': 'https://d.la3-c1cs-cdg.salesforceliveagent.com/chat',
                'eswLiveAgentDevName': 'EmbeddedServiceLiveAgent_Parent0000000jLUAQ_17d9a605e8e',
                'isOfflineSupportEnabled': false
            }
        );
    }
    initESW('https://service.force.com');
</script>
</body>
</html>

getSessionData requires two non-null arguments, meaning your getSessionData(a,b) function is getting null value for a or b or both of them. Why is it getting null, there's something wrong in one of the previous functions which calls getSessionsData() function or you are actually running this function with null data in parameter.
