My page method is returning whole page insted of result from the server side. In my local environment it is working fine but when I deploy it to azure I am getting this problem.

My code is:

function LoadLogsOnSucceeded(result) {
    document.getElementById('divHistoryHeader').innerHTML = result.Header;
    document.getElementById("divHistoryList").innerHTML = result.List;
} 
function LoadLogs() {
    var searchTxt = $("#txtLogsearch").val();
    var maxRecords = $('select[id=drplogSearchMaxRecords]').val(); 
    PageMethods.LoadLogs(searchTxt, maxRecords, LoadLogsOnSucceeded, OnFailed);
}

In config I have not added

<httpModules>

  <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

</httpModules>

when I add that into my config then in local also project is not working getting error like

"The page cannot be displayed because an internal server error has occurred."
