Cant set user status and log user amount from server in discord.js v12 after migrating from v11

Question

Confusing question i know right, but im having this issue after migrating from discord.js v11 to v12 with a bot for my friend.

Im having trouble with getting the amount of user(s) in a server,

Original Code (v11):

client.on("ready", () => {
    console.log(`jthefibot has started, with ${client.users.size} users, in ${client.channels.size} channels of ${client.guilds.size} servers.`);

    client.user.setPresence({
        status: "online",
        game: {
            name: `jt.help for commands | Watching over the jTheFifthElement server with ${client.users.size} members.`,
            type: "Watching"
        }
    }); 
});

Starting bot on v12 throws this error: "size" is not defined"

So in my console i get "bot has started with undefined users in undefined channels" after migrating to v12, in v11, i'd normally get "Bot has started with (12) users in (x) channels"

I just made a migration and had the same problem.

You have to replace:

client.users.size

by

client.users.cache.size

Add also .cache before .channels and .guilds for your other variables.

You can read the documentation here: https://discordjs.guide/additional-info/changes-in-v12.html#managers-cache
