title: Get user avatar from user ID
body: <p>I'm currently developing a birthday announcing bot using discord.js. I wanted to show the avatar of the user, using their Discord user ID to then be used in an embed.</p>
  
  <p>Using <code>client.fetchUser('[userID]').avatarURL</code> currently isn't working.</p>
  
  <pre><code>const exampleEmbed = new Discord.RichEmbed()
      .setColor('#0099ff')
      .setAuthor(' Birthday Announcement:')
      .setThumbnail(cleint.fetchUser('[userID]').avatarURL)
      .setDescription(' Happy day of birth [user ID]! ')
      .setFooter('May 25');
  
  client.on('message', message =&gt; {
      if (message.content.toLowerCase().startsWith('f.test')) {
          message.channel.send(exampleEmbed);
      }
  });
  </code></pre>
  
  <p>It will send the embed alright without the image, but it will give a <code>throw er</code> every few seconds afterwards.</p>
