title: Weird behavior between the Chrome and Firefox
body: <p>I am doing a site using react. The site is using API  /api/auth/login for logging. But for now the database has problem, so the api returns error 500.</p>
  <p>But I got weird issue in Chrome. In Chrome, it shows the CORS error: <a href="https://i.stack.imgur.com/hXhaD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hXhaD.png" alt="enter image description here" /></a></p>
  <p>This is response of OPTIONS:</p>
  <p><a href="https://i.stack.imgur.com/dvqYA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dvqYA.png" alt="enter image description here" /></a></p>
  <p>As we saw in response of OPTIONS: the <code>Access-Control-Allow-Origin</code> is set to <code>*</code></p>
  <p>In Firefox, I can see the response with error 500.</p>
  <p>I don't know why Chrome has different behavior.
  Please share your thinking.</p>
  <p>Thank you.</p>
