I am running the bot in a deno docker container. Bot code:

import { Client, Events, GuildMember } from "discord";

const client = new Client({
    // Numbers since the GatewayIntentBits import does not work in deno for some reason
    intents: [
        1,
        2,
        4,
        512,
        1024,
        4096,
        32768,
        16777216,
        33554432
    ]
});

client.on(Events.GuildMemberAdd, (member: GuildMember) => {
    member.roles.add("1205218206155935754", "Join role");
});

client.login(Deno.env.get("TOKEN"));

import { Client, Events, GuildMember } from "discord";

const client = new Client({
    // Numbers since the GatewayIntentBits import does not work in deno for some reason
    intents: [
        1,
        2,

        4096,
        32768,
        16777216,
        33554432
    ]
});

client.on(Events.GuildMemberAdd, (member: GuildMember) => {
    member.roles.add("1205218206155935754", "Join role");
});

client.login(Deno.env.get("TOKEN"));
