Can't find method com.glide.schedules.Schedule.isInSchedule

[Ethan Davies]

Hi All, 

I am trying to write a Business Rule that compares to the Planned Start Date on a new Change Request. If this Planned Start Date falls within the span of a given schedule then I am marking the Change Request to require CAB approval. 

I was under the impression that I would be able to achieve this using the GlideSchedule.isInSchedule method, but the Business Rule throws up an error stating

Error running business rule 'BR Name' on change_request:CHG0030050, exception: org.mozilla.javascript.EvaluatorException: Can't find method com.glide.schedules.Schedule.isInSchedule(java.lang.String). (sys_script.d88fb97ddb7df3802ffd983cca961982.script; line 19)

I have referred to the official documentation to see if the method I am trying to call still exists, and as of Madrid (current instance family) I can't see any mention of this method being deprecated.

Any pointers would be greatly appreciated. See my code below. 

Thanks,

Ethan

function checkWithinSchedule () {
	var g = new GlideRecord('cmn_schedule');
	g.addQuery('name', '8-5 weekdays');
	g.query();
	if (g.next()) {
	   var sched = new GlideSchedule(g.sys_id);
		
	   var d = new GlideDateTime();
	   d.setDisplayValue("2019-06-03 12:00:00");
		
	if (sched.isInSchedule(d)) {
      gs.info("Is in the schedule");
		return true;
	} else {
      gs.info("Is NOT in the schedule");
		return false;
	}
	}
}

I just copied and pasted the script above in to scripts background on to my Madrid instance and called the function and it worked fine. No errors.

Hi Chuck, 

Thanks for the response. I have also tried running this as a background script and it works correctly. It seems the issue comes from attempting to run it as a Business Rule. I have attached a screenshot of the error. I can't seem to find any mentions of this exact error being reproduced anywhere on community or elsewhere. Will likely end up raising a Hi call.

Can you provide more details/screenshots about the business rule?

[Ethan Davies]

I moved the logic of the business rule into a script include but the same error persists. It's also maybe worth me noting that I am working on a domain separated instance.

Business Rule Details

• When: before (have also tried 'after')
• Order: 100
• Advanced: true
• Runs on: Insert
• No filter or role conditions
• No actions

(function executeRule(current, previous /*null when async*/) {
	// Add your code here
	var newInclude = new CABApprovalRequired();
	newInclude.initialize(current.start_date, current.end_date);
	if (newInclude.checkSchedule()) {
		gs.addInfoMessage('Within Schedule. CAB Required.');
		current.cab_required();
	} else {
		gs.addInfoMessage('Not within schedule. No CAB required');
	}
})(current, previous);

Script Include

var CABApprovalRequired = Class.create();
CABApprovalRequired.prototype = {
    initialize: function(start_time, end_time) {
		this.start_time = start_time;
		this.end_time = end_time;
    },
	
	
	getErrorMsg: function (err) {
		gs.addErrorMessage('Error: '+ current.name);
		gs.addErrorMessage('Error: ' + err);
	},
	
	checkSchedule : function() {
		try {
			var sched;
			var grSchedule = new GlideRecord('cmn_schedule');
			grSchedule.addQuery('name','8-5 weekdays');
			grSchedule.query();
			while (grSchedule.next()) {
				sched = new GlideSchedule(grSchedule.sys_id);
			}
			
			if (sched.isInSchedule(this.start_time) || sched.isInSchedule(this.end_time)) {
				return true;
			}
		} catch (err) {
			this.getErrorMsg(err);
		}
	},

    type: 'CABApprovalRequired'
};

Thanks 🙂
