When refreshing calendar event page, it throws this error

Uncaught TypeError: Cannot call method ‘parse’ of undefined
calendar:239
$.ajax.success calendar:239
fire jquery-1.8.3.js:974
self.fireWith jquery-1.8.3.js:1084
done jquery-1.8.3.js:7803
callback jquery-1.8.3.js:8518

This does happen intermittently. I am parsing JSON object (from the server and it is in the correct format) in the scheduler, below is code snippet

dhx.ready(function () {
dhx.ui.fullScreen();
dhx.ui({
view: “scheduler”,
id: “scheduler”,
container: “scheduler-container”
});

      });

   
    var event = {
        id: '',
        start_date: '',
        end_date: '',
        text: '',
        details: ''
    };

    var model = { event: [] }



    $.ajax({
        type: "POST",
        url: ['@Url.Action](mailto:'@Url.Action)("CalendarEvents")', // add Mobile directory on Dev and Prod
            dataType: "json",
            error: function (xhr) {
                //alert(xhr.responseText);
                alert("Critical Error!. Failed to call the server.");

            },
            success: function (data, jqXHR) {

                // There is no problem with the validation
                if (data.noResult) {
                    alert("no events loaded");
                    return;
                }
                else {
                    //data is not valid display error message
                    model = data.events;
                   
                    scheduler.EnableDataprocessor = true;
                                      
               
                  [b] $$("scheduler").parse(model, "json");
                  // it throws the error exactly after trying to parse JSON object[/b]
                }

            }

        }

I am not sure what is the cause, any idea how I can fix this issue?

Thanks

Please check that $$(“scheduler”) is already created when you are calling parse method. Possibly you need to move $.ajax({…}) into dhx.ready (after scheduler definition).
