        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';
        embedded_svc.init(

        var s = document.createElement('script');
        var jsUlr1 = 'https://ulr.salesforce.com/embeddedservice/5.0/esw.min.js/'
        console.log("Control here2")
        s.src = jsUlr1;
        s.onload = function () {
            initESW(null);
        }
        document.body.appendChild(s);

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>

Hi, I have tried doing it. I kept my html content on `run.mocky.io` and got an url. Now I am getting error `[chromium] [INFO:CONSOLE(7)] "Message origin must match parent origin!", source: https://service.force.com/embeddedservice/5.0/eswFrame.min.js (7)`. I assigned you bounty even before trying this solution so that it wont go unused :). Please help me for this issue? — R15, Mar 23 '22 at 08:53
What happens if you use this URL in a regular desktop browser? Do you have a URL to share that I can inspect? — Jean-Baptiste Martin, Mar 23 '22 at 09:06
When I use same file in w3school online html editor, I can see chat buttons coming up. Not sure why this error coming in mobile application. Above url in comment gives me that error. This is the url I am using https://run.mocky.io/v3/0093032c-1e40-4c0f-bba1-08241a4fed64 — R15, Mar 23 '22 at 09:16
I've just loaded this URL in an Android webview and it works properly: `https://run.mocky.io/v3/b4625e05-9f46-4d93-b1c6-4f12066e931f`. It must be something with your webview config. Can you enable DomStorageEnabled on your webview? Salesforce needs local storage. — Jean-Baptiste Martin, Mar 23 '22 at 09:55

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.
