  <p>I am creating a system that automatically builds up exps when any chat is chatted and level up when certain exps are filled.</p>
  <p>When using <code>@bot.command()</code>, it worked well, but I must enter level to make it work, and when you switch to <code>@bot.event</code> and chat any time, the following error appears:</p>
  <pre><code>AttributeError: 'Message' object has no attribute 'message'
  </code></pre>
  <p>How can I fix the error?</p>
