HELP!!! 'Date must be within the standard change window' error

var CNAChangeHelperAJAX = Class.create();
CNAChangeHelperAJAX.prototype = Object.extendsObject(AbstractAjaxProcessor, {

				return returnValue;
			}
		}

});

I keep receiving this error "Date must be within the standard change window", and I see the error came from this client script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}
	
	if(g_form.getValue('type') == 'standard') {
		g_form.hideFieldMsg('start_date',true);
		var ga = new GlideAjax('CNAChangeHelperAJAX');
		ga.addParam('sysparm_name','isWithinStandardWindow');
		ga.addParam('sysparm_cr_sys_id',g_form.getUniqueValue());
		ga.addParam('sysparm_date_format',g_user_date_time_format);
		ga.addParam('sysparm_date',newValue);
		ga.getXML(StartDateParse);
	}
	
	function StartDateParse(response) {
		var answer = response.responseXML.documentElement.getAttribute("answer");
		if(answer != 'true') {
			g_form.clearValue('start_date');
			g_form.showFieldMsg('start_date','Date must be within the standard change window','error');
		}
	}}

 I tried with different hours but I keep receiving the same error, and I'm not able to see why this happening in there any error on the code?
I'm trying to schedule a time with a standard change request

Hi @Abigail ,

Check proposal is not empty

isWithinStandardWindow: function() {
    var crSysID = this.getParameter('sysparm_cr_sys_id');
    gs.log("Value crSysID: " + crSysID);
    var compareDate = this.getParameter('sysparm_date');
    gs.log("Value: " + compareDate);
    var format = this.getParameter('sysparm_date_format');
    var changeRequest = new GlideRecord('change_request');
    
    if (changeRequest.get(crSysID)) {
        var producer = changeRequest.std_change_producer_version;
        
        if (!producer.nil()) {
            var proposal = producer.std_change_proposal;
          
            if (proposal) {
                var schedule = new GlideSchedule(proposal.u_schedule.sys_id);
                var date = new GlideDateTime();
                date.setDisplayValue(compareDate, format);
                // date.add(-date.getTZOffset());
                var returnValue = schedule.isInSchedule(date);
                return returnValue;
            }
        }
    }
    
    gs.log("Failed to determine if date is within the standard change window.");
    return false;
},

Please mark it as solution proposed and helpful if it serves your purpose.

Thanks,

Anand

How i can check the proposal time?

[Anand Kumar P]

@Abigail ,

Try above script i am saying proposal not empty in if condition.

if (proposal) {
                var schedule = new GlideSchedule(proposal.u_schedule.sys_id);

Thanks,

Anand

Hello @Anand Kumar P 

I still received the same error

And this does not happen with all standard changes only with a few
