Discord.js: setNickname Error

[Juceztp]

Hello, i just want to change the nickname of a user on a specific role.

Code:

var Discord = require("discord.js");

var mybot = new Discord.Client({forceFetchUsers: true});

mybot.on("message", function (message) {
    'use strict';
    if (message.content === "nickname") {

        var list_users = message.server.usersWithRole(message.server.roles.get("name", "role"));

        mybot.setNickname(message.server, "LoremIpsum", list_users[1], function (error) {
            if (error) {
                console.log(error);
            } else {
                console.log("done!");
            }
        });

    }
});

mybot.loginWithToken("token");

debugging error:

You can't modify the nickname of people whose highest role is the same or higher than your highest role.
