How to get the value of a field in a javascript file in a script report

frappe.query_reports[“Employee Checkin Summery”] = {
“filters”: [
{
“fieldname”:“employee”,
“label”: __(“Employee”),
“fieldtype”: “Link”,
“options”: “Employee”,
“reqd”:1
},
{
“fieldname”:“fromdate”,
“label”: __(“From Date”),
“fieldtype”: “Date”,
“default”: frappe.datetime.get_today(),
“reqd”:1
},
{
“fieldname”:“todate”,
“label”: __(“To Date”),
“fieldtype”: “Date”,
“default”: frappe.datetime.get_today(),
“reqd”:1
},
{
“fieldname”:“shift_sett”,
“label”: __(“Shift Settings”),
“fieldtype”: “Link”,
“options”: “Shift Settings”,
“reqd”:1
}
],

formatter: function(value, row, column, data, default_formatter) {
	value = default_formatter(value, row, column, data);

	
	if (column.fieldname == "in_iime") {
		let shift_start = frappe.db.get_value('Shift Settings', data.shift_sett , 'start_time');
	  if (data.in_iime || shift_start){
		console.log(data.in_iime);
		console.log(shift_start);
	  }
	  if (data.in_iime > shift_start) {
		
		value = "<span style='background-color: #e12b2b; color:white;'><b>&nbsp;" + value + "&nbsp;</b></span>";
	  } 
	}
	return value;
  }
};

Why doesn’t it fetch field value (shift_start)
Please help and thank you very much
