The exception throw in the suitescript 2.0 for creating a saved search of kit package.

Hello NetSuite Guru team,

I wrote a script as below but it threw the error "org.mozilla.javascript.EcmaError: TypeError: Cannot find function toLowerCase in object CASE WHEN {memberitem.locationquantityonhand} >0 THEN 'in stock' ELSE 'out of stock' END. (N/search/searchObject.js#1989)"

Could you please review the screenshots I attach below and let me know what is wrong with this?

/**

 * @NApiVersion 2.x

 */

require(['N/search','N/file'], function(search,file) {

   //kititem

var columns = [

search.createColumn({ name: 'internalid', label: 'SKU', summary: 'GROUP' }),

search.createColumn({

name: 'formulatext',

formula: [

"CASE WHEN {memberitem.locationquantityonhand} >0 THEN 'in stock' ELSE 'out of stock' END"

],

summary: 'MAX',
