title: Express JS changing line break type to CRLF
body: <p>I am trying to make a HTTP request from a Flutter App to a Express-JS Server running on an Ubuntu machine. A newer version of Flutter(v1.22.5) throws following error when making the Request:</p>
  <p><code>E/flutter (29477): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: Invalid response, unexpected 10 in reason phrase</code></p>
  <p>The code for making the request looks like this:</p>
  <pre class="lang-dart prettyprint-override"><code>final response = await http.get(
                        'http://XX.XX.XXX.XXX/employees', //Hiding IP address for privacy purposes
                        headers: {
                          &quot;Content-Type&quot;: &quot;application/json&quot;,
                          &quot;Authorization&quot;: api_key,
                        },
                      );
                      print(response.statusCode);
  </code></pre>
  <p>I can confirm by using HTTP-Tester Insomnia that the queried URL does indeed return information.</p>
  <p>The issue seems to be known and can be viewed <a href="https://github.com/dart-lang/sdk/issues/43916" rel="nofollow noreferrer">here</a></p>
  <p>According to the Github-Thread, the issue is due to wrong line break format in the headers.
  How can I tell Express JS to use CRLF?</p>
