类型错误：无法读取未定义的属性“添加”，Discord.JS

Question

client.on('message', message => {
  if (message.content.startsWith(prefix + 'sanitar')) {
    if (message.member.hasPermission('ADMINISTRATOR')) {
      const user = message.mentions.users.first();
      if (user != undefined) {
        user.GuildMemberRoleManager.add(635602511964667907);
        message.channel.send(`<:mebel:632608605635608578> | Пользователь ${user} был отправлен в дурку ебать!`);
      } else {
        message.channel.send('<:mebel:632608605635608578> | Пингани кого-то, идиот.');
        message.channel.send('<:debil:691052950998482955>');
      }
    } else {
      message.channel.send('<:mebel:632608605635608578> | У вас недостаточно прав для этого действия!');
    }
  }
});

I'm trying to create an add-role command for my discord.js bot, but when it gets to user.GuildMemberRoleManager.add(635602511964667907);

i get:

TypeError: Cannot read property 'add' of undefined.

I also tried to use user.Addrole function, but i get:

user.Addrole is not a function.

Maybe addrole is outdated now, idk. I am very tired of this, so can somebody help me to fix it pls...

Answer 1

You need to use roles not GuildMemberRoleManager since roles returns GuildMemberRoleManager of the GuildMember .

Also User does not have roles only GuildMember does so you have to replace const user = message.mentions.users.first(); with const user = message.mentions.members.first();

You also need to pass the role ID as a string, not a number.

user.roles.add('635602511964667907');

Also, you are correct, addRole() is not a function and has deprecated since discord.js v12.
