title: Sending message to specific channel, not working
body: <p>Having trouble sending a bot message on a specific channel. I very simply want to have the bot send a message to #general when it activates, to let everyone know it's working again.</p>
  
  <p>In the bot.on function, I've tried the classic client.channels.get().send(), but the error messages I'm getting show that it thinks client is undefined. (It says "cannot read property 'channels' of undefined")</p>
  
  <pre><code>bot.on('ready', client =&gt; {
      console.log("MACsim online")
      client.channels.get('#general').send("@here");
  })
  </code></pre>
  
  <p>The bot crashes immediately, saying: Cannot read property 'channels' of undefined</p>
