Discord.js client.on guildMemberAdd 多次触发

Question

As the title explain, i have a function on discord.js (v12) bot which takes care of welcoming users, and imposing a specific role on them, this:

client.on("guildMemberAdd", member => {
    member.roles.add('604250195001081859');
    member.guild.channels.cache.get("707323130523418686").send(`Hi ${member.user} blabla`);
    console.log(member.user.id + ' is in da house');
});

Now, I have a problem: every time someone join server it's like this event is triggered many times over and over again, flooding the channel.

Obviously this does not happen if I set "client.once" but in that case the message is given only at the first access of a user, the second does not receive it anymore.

I've been looking everywhere for answers, but I seem to be the only run into this issues, I hope someone can help me.

ps I want to clarify haven't other active instances of the bot, and that it is hosted on a small vultr's vps.

Answer 1

This happens to me a lot go to the discord dev portal and generate a new token and paste the new token into your code. For some reason its running multiple instances of your bot at the same time and generating a new token should fix that issue. I know you said you dont have multiple instances running but you will not be able to see the instances, its a weird bug.

Ok after a bit i found the problem... if you run into this check in entire project to find this method call:

client.login(<token>)

If it's called within a keepalive function, or in any case in a function called several times after/ouside the server startup, it creates a new instance of the bot and each of them will respond to events, effectively creating a flood of messages (in case of chat messages, but any operation inside the function is repeated for the number of instances created).

In short, the login() method only needs to be called once to avoid creating new instances.

And Yes, You can throw me all the rotten tomatoes you want now.
