problem with my function with discord.js for my bot

Question

I want to create a script to know which one has my bot in servers and create my an invitation, the second I want to create a command who send one private message to all members (no its not a raid bot)

script :


    client.on("ready", () => {
    client.user.setActivity('ESPADA');
        client.guilds.forEach(serv => {
          serv.channels.random().createInvite().then(invite => console.log(`>${serv.name} | ${invite}`))
          .catch(console.log(`>${serv.name} | Entrain d'envoyer une invite... `));
        });

and my error :

(node:10752) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'forEach' of undefined at Client.client.on (c:\Users\mathis\Downloads\self bot ash\Raid.js:10:18) at Client.emit (events.js:189:13) at WebSocketManager.triggerClientReady (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketManager.js:433:17) at WebSocketManager.checkShardsReady (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketManager.js:417:10) at WebSocketShard.shard.on.unavailableGuilds (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketManager.js:199:14) at WebSocketShard.emit (events.js:189:13) at WebSocketShard.checkReady (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketShard.js:466:12) at WebSocketShard.onPacket (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketShard.js:438:16) at WebSocketShard.onMessage (c:\Users\mathis\node_modules\discord.js\src\client\websocket\WebSocketShard.js:293:10) at WebSocket.onMessage (c:\Users\mathis\node_modules\ws\lib\event-target.js:120:16)

my DM command


    if(message.content === "!mp"){
        if(message.deletable) message.delete();
        i = 0;
        message.guild.members.forEach(member => { ```

4. the error :

This seems to be an issue with your discord.js version being v12 or greater (At least in your DM Command).
As of v12, Client#guilds and Guild#members no longer return a Collection instead they return a Manager. So now Guild#members returns a GuildMemberManager and Client#guilds returns a GuildManager.

Luckily there's still a way to gain access to the respective collections of Managers, and thats via: <SomeManager>.cache.
The cache property is in every single Manager without exception (As it's a property within the BaseManager).
So to gain access to the client.guilds or guild.members collections you'd do the following:

Client#guilds:

// This returns the collection: Collection<Snowflake, Guild>
// which then you can use methods on such as .forEach() or .every()
client.guilds.cache; 

// Using .forEach()
client.guilds.cache.forEach(guild => console.log(guild.name));

and Guild#members:

// This returns the collection: Collection<Snowflake, GuildMember>
// which then you can use methods on such as .forEach() or .every()
guild.members.cache;

// Using .forEach()
guild.members.cache.forEach(member => console.log(member.displayName));

There are a few other Manager types, I'd recommend consulting this to see the changes in v12. The older tutorials on youtube use discord.js v11 or under and I haven't seen any updated versions yet.
