Node JS Undefined Variable In Argument

Question

let args = message.content.slice(config.prefix.length).split(' ');
let command = args.shift().toLowerCase();
let tellJoke = randomNumber(4);

if (debounce == true){
    return
  }
debounce = true

switch (command) {

  case 'gameid':
    console.log(args.length)
    if(args.length == 1){
      let placeId = args[1]
      console.log(placeId)
      api = await fetch("https://api.roblox.com/universes/get-universe-containing-place?placeid=" + placeId)
      let gameId = await api.json()
      try{
        if(api){
          reply = await message.reply('Game Id: ' + gameId.UniverseId)
          debounce = false
          break;
        }
      }catch(error){
        reply = await message.reply('Something went wrong. ERROR: ' + error);
        debounce = false
        break;
      }

      }
    reply = await message.reply('Something went wrong. Did you write the command correctly?')
    debounce = false
    return

It says placeId/arg 1 is undefined when I clearly put the place id there. Does anyone know why this is happening? I've printed/logged the args and length of it and I can say that it should work.

If args.length == 1 then args[1] is undefined. args[0] is the first element in an array (and the only element in an array of length 1). — Dave Newton

Array index starts from 0. so if the length of the array is 1 you can access the first element with args[0].

let args = message.content.slice(config.prefix.length).split(' ');
let command = args.shift().toLowerCase();
let tellJoke = randomNumber(4);

if (debounce == true){
    return
  }
debounce = true

switch (command) {

  case 'gameid':
    console.log(args.length)
    if(args.length == 1){
      let placeId = args[0]
      console.log(placeId)
      api = await fetch("https://api.roblox.com/universes/get-universe-containing-place?placeid=" + placeId)
      let gameId = await api.json()
      try{
        if(api){
          reply = await message.reply('Game Id: ' + gameId.UniverseId)
          debounce = false
          break;
        }
      }catch(error){
        reply = await message.reply('Something went wrong. ERROR: ' + error);
        debounce = false
        break;
      }

      }
    reply = await message.reply('Something went wrong. Did you right the command correctly?')
    debounce = false
    return

Thank you! Makes more sense now why it would say undefined.
