Need Help with first 2.0 Script FTP

@NApiVersion

Hello,

I am trying to do my first 2.0 script, and it is just downloading a file from an FTP. I made it a scheduled search and when I try to run it at the debugger I get the following:

Cannot find function createConnection in object [object Object].

 /**   * @NApiVersion 2.x   * @NScriptType ScheduledScript   * @NModuleScope SameAccount   */  define(['N/file','N/sftp'],  /**   * @param {file} file   * @param {sftp} sftp   */  function(sftp,file) {        function execute(context) {            var myPwdGuid = "XXXXXXXXXX";          //var myHostKey = "XXXXXXXXXXXXXX";            var connection = sftp.createConnection({              username: 'usernameXX',              passwordGuid: myPwdGuid, // references var myPwdGuid              url: 'sft.testnet',              directory: '/Outbound/',              hostKey: myHostKey          });            // download the file from the remote server            var downloadedFile = connection.download({              directory: '/Outbound/',              filename: 'test.csv'          });      }        return {          execute: execute      };    });
