我的代码，我不知道问题出在哪里，谁能帮助我

function sendTextMessage(recipientId, messageText) { 
let text = messageText.toLowerCase();
// Get Data From a Google Sheet
var google_sheet_json = "https://spreadsheets.google.com/feeds/list/" + 
process.env.GOOGLE_SHEET_ID +"/od6/public/values?alt=json";
request.get(google_sheet_json, function (err, res, body) {
 if (!err) {
  var bot_script_obj = JSON.parse(body);
  var all_bot_scripts = bot_script_obj.feed.entry;

  var i = 0;
  var len = all_bot_scripts.length;
  var all_keywords = [];
  for (; i < len; ) {

    if (text.includes(bot_script_obj.feed.entry[i].gsx$incoming.$t)){
      var messageText = bot_script_obj.feed.entry[i].gsx$outgoing.$t;
      var messageData = {
        recipient: {
          id: recipientId
        },
        message: {
