Script do nothing - google-apps-script

Question

I'm trying to write code to save data and read data from telegram to google sheets using this code
function sendText(id,text) {
var url = telegramUrl + "/sendMessage?chat_id=" + id + "&text=" + text;
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function doPost(e) {
var data = JSON.parse(e.postData.contents);
var id = data.message.chat.id;
var username = data.message.chat.username;
var date = Utilities.formatDate(new Date(), "GMT+9", "dd/MM/yyyy");
var hour = Utilities.formatDate(new Date(), "GMT+9", "HH:mm:ss");
var text = data.message.text;
if (text.startsWith("/start")) {
sendText(id,"Hello " + username + ", welcome to my bot");
} else if (text.startsWith("/input")) {
const text = String(data.message.text).replace("/input ", "");
var item = text.split(",");
var sheet = SpreadsheetApp.openById(ssId).getSheetByName(sheet1);
sheet.appendRow([date,hour,id,username,item[1],item[2],item[3],item[4],item[5],item[6],item[7],item[8],item[9]]);
sendText(id,"data has been saved");
} else if (text.startsWith("/search")) {
const text = String(data.message.text).replace("/search ", "");
var keyword = text.split(" ");
var sheet = SpreadsheetApp.openById(ssId).getSheetByName(sheet2);
var data = sheet.getRange("A2:E").getValues();
var found = false;
for (var i = 0; i < data.length; i++) {
if (data[i][0] == keyword[1]) {
sendText(id, "Data found!\n" + "data1 = " + data[i][0] + "\n" + "data2 = " + data[i][1] + "\n" + "data3 = " + data[i][2] + "\n" + "data4 = " + data[i][3] + "\n" + "data5 = " + data[i][4]);
found = true;
}
}
if (!found) {
sendText(id,"data not found");
}
} else if (text.startsWith("/help")) {
sendText(id,"/input (date, hour, id, username, item[0], item[1], item[2], item[3], item[4], item[5], item[6], item[7])\n/search (keyword)");
}
}
I have tried to use openAi chat to help fix my code, but still not work.
