I have created user event script. But its not updating the record by traying many ways. please help!

/**

• @NApiVersion 2.x

• @NScriptType UserEventScript
  */
  define([‘N/record’, ‘N/https’, ‘N/log’], function(record, https, log) {

  function afterSubmit(context) {
  if (context.type === context.UserEventType.EDIT) {

       var city='Mumbai';
  
       try {
           // Get access token for Salesforce
           var accessToken = getSalesforceAccessToken();
           log.debug("Access Token", accessToken);
  
               if (!accessToken) {
               throw new Error('Failed to get access token from Salesforce');
           }
  
  
            //Update customer in Salesforce
           var salesforceResponse = updateSalesforceCustomer(accessToken, {
               City__c : city
           });
           log.debug("salesforceResponse",salesforceResponse);
  
  
           if (salesforceResponse.success) {
               log.debug("Customer Created in Salesforce", "Customer ID: " + salesforceResponse.id);
           } else {
               throw new Error('Failed to create customer in Salesforce: ' + JSON.stringify(salesforceResponse.error));
           }
       } catch (e) {
           log.error('Error creating customer in Salesforce', e.message);
       }
