TypeError: member.roles.add is not a function (discord.js v13)-CodePudding

I'm working on a bot that needs to check some things before giving/removing a role from a user, but for some reason, the .has(), .some(), .add() and, .remove() functions don't work.

Here's my code:

const Permissions = require('discord.js');

function isAdmin(member) {
    return member.permissions.has(Permissions.FLAGS.ADMINISTRATOR);
}

function hasRole(member, roleID) {
    return member.roles.some(role => role.id === roleID);
}

function giveRole(member, role) {
    member.roles.add(role)
}

function removeRole(member, role) {
    member.roles.remove(role);
}

Here's the full error that I get:

CodePudding user response：

In Discord.js version 12, the syntax mostly changed. The cache property now contains the cache for a lot of the roles, and there is a chance you need to use a Promise and fetch it...

// in an ASYNC FUNCTION
let roles = await member.roles.cache.fetch();
return roles.some(role => role.id === roleID);

CodePudding user response：

When doing anything with roles, and most stuff in general, you need to access it via the cache, for example:

  function hasRole(member, roleID) {
      return member.roles.cache.some(role => role.id === roleID);
  }

CodePudding user response：

Did you tried like this?

var role = message.guild.roles.cache.find(role => role.name === "Role_Name")
member.roles.add(role)

var role = message.guild.roles.cache.find(role => role.id === "Role_Id")
member.roles.add(role)
