Javascript Error for Polyfill happening only in Chrome Incognito Mode

[NAVEEN RAAJU]

Hi,

 We encountered a strange issue where Data Grid Load is not working only in Chrome Incognito Mode. However, the grid works in all other browsers (both normal and private mode). 

 I can see the below error from the console. 

Uncaught TypeError: Illegal constructor

    at HTMLDivElement.<anonymous> (polyfill.min.js:3)

    at D (ej2.min.js:10)

    at t.appendTo (ej2.min.js:10)

    at index.js:109

polyfill.min.js:3 Uncaught TypeError: Illegal constructor

    at HTMLDivElement.<anonymous> (polyfill.min.js:3)

    at D (ej2.min.js:10)

    at t.appendTo (ej2.min.js:10)

    at Object.success (brokerchartindex.js:39)

    at c (jquery-3.4.0.min.js:2)

    at Object.fireWith [as resolveWith] (jquery-3.4.0.min.js:2)

    at l (jquery-3.4.0.min.js:2)

    at XMLHttpRequest.<anonymous> (jquery-3.4.0.min.js:2)

It works fine when i just run an html file with Data Grid in Incognito Mode. But for some reason, it does not work when we access the application with Data Grid deployed in AWS only in Incognito Mode. 

I have attached the jsp file and the JS file which loads the JavaScript.

Please let me know if anything else is required.

Hi Naveen, 

Thanks for contacting Syncfusion. 

Before proceed your requirement, Please share the below details, 

1. What kind of requirement did you use Polyfill in your application?
2. Share your running application because your reported files have lack of our dependencies. So, we can’t run and check it.
3. Video demonstration of your issue.

Please get back to us, if you need any further assistance.

Hi,

The Grid does not work in IE . Hence , we included polyfill js as part of the page . This made it work for IE.

Temporarily, we have disabled the polyfill js in all browsers except IE. I will test it and let you know.

I will upload a video demonstration if this solution does not work.

We made a change to load the polyfill script only in IE browsers. So its now working fine in chrome incognito mode. Thanks for your assistance.
