Cannot read property fetch of undefined

My friend originally said this as a joke, but he told me to make my own discord bot, so here I am weeks later actually doing it because I found fun in it. So whenever I run this it just gives me the error that it," cannot read the property fetch of undefined" The Bot is operational with other commands, this is meant as an expansion for future functions. Additionally it is hosted off of a raspberry pi with nodemon --inspect

Here is my code:

const guild = client.guilds.fetch("xxxxxxxxxxxxxx");
var memberList = [];
var randomInt = new Number(0);
var User = {
    id: 0,
    FollowUp: 0,
    name: "Tes",
    statement: ""
};
var Person = {};

function myFunction(value) {
    const id = new Number(0);
    id = value.id;
    Person[id] = new User();
    Person[id].id = value.id;
    Person[id].name = value.user.username;
    Person[id].statement = "";
    Person[id].FollowUp = new Number(0);
}

client.on('ready', () => {
    console.log('Ready!');
    memberList = guild.members.fetch();
    memberList.forEach(myFunction);
});

Here are the error logs:

As the error suggests, it can't read the property fetch of undefined, meaning the guild is undefined. I can spot 2 issues:

  1. Client can't be accessed before it's ready. Move your const guild = client.guilds.fetch("xxxxxxxxxxxxxx"); inside the client.on("ready" listener.
  1. Replace client.guilds.fetch("xxxxxxxxxxxxxx"); with client.guilds.cache.get("xxxxxxxxxxxxxx");, using .get() on a cache collection. I hope that helped!
