title: Discord JS Client only has itself in guild members cache
body: <p>So I was trying to access a member from a guild via</p>
  <pre><code>client.guilds.cache.find((guild) =&gt; guild.id === id).members.cache.find((member) =&gt; member.user.username === name)
  </code></pre>
  <p>but when the bot starts up the guild only contains itself until a user sends a message.</p>
