I'm facing a tough problem with my ASP.NET web app that uses AJAX. When I press the submit button on my webpage, I'm getting an error that says "Uncaught RangeError: Invalid array length." Oddly, even though this error occurs, the data I need is showing up correctly on the page. The trouble is, the page keeps loading forever, and the "please wait" message never disappears. It's also showing an error in the browser's console.

}
When I click the 'Submit' button in my application, it triggers an AJAX call, and I'm encountering an error on the client side. I've verified that it's not a server-side error while debugging. The peculiar thing is that I'm not explicitly using any JavaScript code in my application. Is there a method to handle these client-side errors effectively?

<ajax:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />

<ajax:AsyncPostBackTrigger ControlID="chkRefresh" EventName="CheckedChanged" />
<ajax:AsyncPostBackTrigger ControlID="chkHighlightEnable" EventName="CheckedChanged" />
</Triggers>
Here are the screenshot of the error:
I tried to debug online and when i first open the page i can see Array value is =134
But when i click on button submit it shows Array value = 135
