I can't get huge texts

[Fenish]

when i try to get huge texts with javascript, it cames null.
for example i am httprequesting to website and im getting result with js, when i check console, its perfect but when i debug with msgbox.show, it comes nothing.

Os: windows 7
Cefsharp version: 88.2.90.0
Platform: winforms
Cpu: x86

Code

...
.....
         mainform.browser.ExecuteScriptAsync("var obj = $.get('requested_website');");
         JavascriptResponse result = JsScriptResult("obj['responseText']", 1000);
         MessageBox.Show("Result:" + result.Result.ToString() + "\nMessage: " + result.Message);


        private JavascriptResponse JsScriptResult(string script, int timeout)
        {
            IFrame frame =  mainform.browser.GetMainFrame();
            Task<JavascriptResponse> Task = frame.EvaluateScriptAsync(script, timeout: TimeSpan.FromMilliseconds(timeout));
            Task.Wait();
            return Task.Result;
        }

but when i manually type obj['responseText'] to console, it comes perfect.
And also when i try to do this, it comes perfectly

Code 2

         mainform.browser.ExecuteScriptAsync("var dadada = '3131' ");
         JavascriptResponse result = JsScriptResult("obj['responseText']", 1000);
         MessageBox.Show("Result:" + result.Result.ToString() + "\nMessage: " + result.Message);

How can i get result of request webpages.
Original obj['responseText'] is kinda like that

<xml>
   <item id="69" name="blabalbal">
</xml>

Use http://cefsharp.github.io/api/89.0.x/html/Overload_CefSharp_WebBrowserExtensions_EvaluateScriptAsPromiseAsync.htm and wrap your Ajax call in a promise. See #3251 for further details.
