Hi,

You code should be like this:

Note: Read the comment in line 3 and update code accordingly

isContainsRetiredCIs: function(change_request) {
	var taskGR = new GlideRecord('task_ci');
	taskGR.addQuery('task',change_request); // Use this line if change_request has sys_id. If it has Change Number then comment this line and uncomment next line
	//taskGR.addQuery('task.number',change_request); 
	taskGR.addQuery('ci_item.operational_status','1'); // Check if operational status is Operational 
	taskGR.query();
	return taskGR.hasNext(); // Return true if record returned. Otherwise return false
};
},
