如何为用户添加角色

Question

我在网上看过一些指南，他们大多使用这个命令

let role = message.guild.roles.cache.find(r => r.id === "Role ID");
// The member you want to add the role to
let member = message.mentions.members.first();
// Add role to the member
member.roles.add(role);
// Or add it to yourself
message.author.roles.add(role);

我尝试了很多次这是我实现的代码

if (message.member.roles.cache.some(role => role.name === "Co-Owner" || role.name === "Operator")) {
if (command == "birthday") {
const mention = message.mentions.users.first() || client.users.get(args[0]);
var role = message.guild.roles.cache.find(role => role.name === "BIRTHDAY POG");
if (mention.roles.cache.some(role => role.name === "BIRTHDAY POG")) {
message.reply("The user has already the role, the role will now be removed");
mention.roles.remove(role);
}
else {
mention.roles.add(role);
message.reply("The role has been added to `" + mention.username + "`");
client.guilds.cache.get('731368965963513936').channels.cache.get('778124805135663104').send(message.author.username + " has used the command Birthday to " + mention.username);
message.reply("Use the same command with the person to remove the role");
}
}
}

这个命令应该为提到的用户添加生日角色，但是我不能使它工作，它给出了这个错误

if (mention.roles.cache.some(role => role.name === "BIRTHDAY POG")) {
^
TypeError: Cannot read property 'cache' of undefined

有人能帮我一下吗?

但基本上，你需要改变

message.mentions.users.first() || client.users.get(args[0]);

message.mentions.members.first() || message.guild.members.cache.get(args[0])
