uptime (Broken)

const Discord = require("discord.js");
const moment = require('moment');
require('moment-duration-format');
exports.run = (client, message, args) => {
    const embed = new Discord.RichEmbed()
      .setTitle("Bot Uptime")
      .addField('Uptime:', moment.duration(client.uptime).format('d [days], h [hours], m [minutes], s [seconds]', { trim: "small" }), true)
      .setColor(0x00A2E8)
     message.channel.send(embed)
}
