Pulling out "text" from JSON – Telegram API

I am writing a google app script that works with telegram. The user will key in their unique 4 digit code and it will run against my array. i have most of the stuff working. I’m currently stuck getting my code to match the users input.

from the JSON below. i am only able to extract the first result in my syntax.

for example extracting the chatid

var contents = JSON.parse(e.postData.contents)
var id = contents.message.from.id

But what i am trying to extract is the "Welcome" from the text portion of the 2nd response.

{
  "ok": true,
  "result": [
    {
      "update_id": 11111111,
      "message": {
        "message_id": 412,
        "from": {
          "id": 22222222,
          "is_bot": false,
          "first_name": "don",
          "username": "king",
          "language_code": "en"
        },
        "chat": {
          "id": 333333333,
          "first_name": "Don",
          "username": "king",
          "type": "private"
        },
        "date": 1600865179,
        "text": "Test"
      }
    },
    {
      "update_id": 111111111,
      "message": {
        "message_id": 413,
        "from": {
          "id": 1111111111,
          "is_bot": false,
          "first_name": "Don",
          "username": "king",
          "language_code": "en"
        },
        "chat": {
          "id": 44444444,
          "first_name": "don",
          "username": "king",
          "type": "private"
        },
        "date": 1600865186,
        "text": "Welcome"
      }
    }
  ]
}

This is the main part of my script that has difficulty. I was able to log and confirm it works and generates the values and array i need. However when i send an input to telegram it stops at "Please Wait".

function doPost(e){
    var contents = JSON.parse(e.postData.contents);
    var id = contents.message.from.id;
    sendMessage(id, "Please wait");
    var userInput = contents.result[1].message.text;
    var ssId = "XXXX";
    var sheet = SpreadsheetApp.openById(ssId).getSheetByName("Sheet1");
    var idArr = sheet.getRange("A2:A").getValues();
    idArr = idArr.map(row => row[0]);
    var idIndex = idArr.indexOf(userInput);
     if(userinput == idArr){
        let rowNumber = idIndex + 3;
        let colNumber = 4; //col D
        var dateNow = new Date;
        sheet.getRange(rowNumber, colNumber).setValue(dateNow);
        sendMessage(id, "You have successfully registered");
        
    }
    else{
        
sendMessage(id, "user not found");

    }
  
}
