Why is inventory location field not being set?

Hi There

I have cross subsidiary fulfilment enabled in NetSuite.

I am trying to set the field value for the item sublist field id: inventorylocation

However, it cannot be set. No error is returned but this field remains unchanged while all the other fields in the item sublist can be set using the same client script.

The script

/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 */

// Define the dependencies required for the client script
define(['N/currentRecord'], function (currentRecord) {

  // Function triggered when a field is changed
  function fieldChanged(context) {
    // Get the current record object
    var currentRecordObj = currentRecord.get();
    log.debug('currentRecordObj',currentRecordObj)

    // Get the sublist ID that triggered the event
    var sublistId = context.sublistId;

    // Get the ID of the field that triggered the event
    var fieldId = context.fieldId;

    // Log the sublist ID and field ID for debugging
    log.debug({
      title: 'Sublist ID',
      details: sublistId
    });

   console.log(sublistId)
    log.debug({
      title: 'Field ID',
      details: fieldId
    });

    if (fieldId == 'item') {
      // Get the line number of the currently selected line in the 'item' sublist
      var lineNumber = currentRecordObj.getCurrentSublistIndex({
        sublistId: 'item'
      });
      log.debug('lineNumber', lineNumber);
     console.log(lineNumber)
   

     Set the value of the 'itemlocation'
