client.on('ready', () => {
arrayID = ['DISCORD_ID'];
guild.members.fetch(arrayID[0]).then(member => {
return guild.roles.fetch('ROLE_ID');
}).then(role => {
return member.roles.add(role);
}).catch((err) => {
});
});
With that code I am receiving the error: guild is not defined because of that I tried it with
client.guild.members.fetch(arrayID[0]).then(member => {
But then I am receiving the error: Cannot read properties of undefined (reading 'members')
The problem is you haven't defined your guild variable, that's why you received the error "guild is not defined". The other one is because client doesn't have a guild property.
Don't forget that your bot can be in different guilds. You can get these guilds using client.guilds. It returns a GuildManager and its cache returns a collection.
If you know your guild ID, you can get the guild like this:
let guild = client.guilds.cache.get('YOUR_GUILD_ID')
If your bot is only in a single guild, you could grab the first() one in this collection:
let guild = client.guilds.cache.first()
Once guild is defined, the rest of your code should work, although you should log the error in your catch block. Oh, and member won't be available in your second then, so you should fix that too.
You could use async/await to make it more readable:
client.on('ready', async () => {
let arrayID = ['DISCORD_ID'];
let roleID = '928938568624263178';
let guild = client.guilds.cache.get('GUILD_ID');
try {
let member = await guild.members.fetch(arrayID[0]);
let role = await guild.roles.fetch(roleID);
if (!member) return console.log(`Can't find member with ID "${arrayID[0]}"`);
if (!role) return console.log(`Can't find role with ID "${roleID}"`);
member.roles.add(role);
} catch (err) {
console.log(err);
}
});
