  <p>I use tweepy (4.8.0) and auth 2.0 (bearer_token)</p>
  <p>I tried to load user information by using <strong>get_user(...)</strong> like this</p>
  <pre><code>client = tweepy.Client(
      bearer_token=bearer_token
  )
  result = client.get_user(username=&quot;name&quot;, user_fields=['created_at'])
  </code></pre>
  <p>I expected to get additional data put in the <strong>user_fields</strong>, but only simple basic data was passed.</p>
  <pre><code>Response(data=&lt;User id=1234 name=NAME username=name&gt;, includes={}, errors=[], meta={})
  </code></pre>
  <p>Maybe I'm missing something or made a mistake?</p>
  <p>save me plz...</p>
