Everytime I run the discord bot, it says that the number of online members is undefined

Question

This is the code

 module.exports = async (client) => {
        let myGuild = client.guilds.cache.get(guild.id)

            setInterval(() =>{

            var onlineCount = myGuild.members.cache.filter(member => member.presence?.status != "offline").size
    
            let memberCountChannel = myGuild.channels.cache.get(channel.id);
            console.log(onlineCount.name);
            memberCountChannel.setName(onlineCount + 'people online')
            .then(result => console.log(result))
            .catch (error => console.log(error));
        }, 5000)
    }

And this is the part that counts the members

var onlineCount = myGuild.members.cache.filter(member => member.presence?.status != "offline").size

What the terminal shows

undefined
undefined
undefined
undefined
undefined

filter method returns an array, and arrays do not have size property. Use length property and it will be ok.

var onlineCount = myGuild.members.cache.filter(member => member.presence?.status != "offline").length

`.members.cache` is a Collection instance (https://discord.js.org/#/docs/main/stable/class/GuildMemberManager?scrollTo=cache) and not an array. – Leau Dec 23 '21 at 18:26
Doesn't work still says undefined – SlendyX Dec 23 '21 at 21:14

Since you are restarting the bot the data is not cached, you firstly need to fetch the members with <Guild>.members.fetch method. Else it means you didn't activate intents, refer here.

Example for your case:

await myGuild.members.fetch();
var onlineCount = myGuild.members.cache.filter(member => member.presence?.status != "offline").size;

Could u please give me an example of how to do it? I haven't used this method before – SlendyX Dec 23 '21 at 21:19
await myGuild.members.fetch(); – Leau Dec 23 '21 at 21:20
Before accessing the cache. – Leau Dec 23 '21 at 21:20
Don't I need an async function to use await? – SlendyX Dec 23 '21 at 21:55
Yes don't forget to put your `setInterval` function in `async` too. – Leau Dec 23 '21 at 22:03
