body: <p>I'm debugging my app via WiFi. It installs successfully but I got a red screen with an error:</p>

  <p>The documentation says that I should <a href="https://facebook.github.io/react-native/docs/running-on-device#method-2-connect-via-wi-fi" rel="nofollow noreferrer">set debug host and port</a> but there is no "Debug server host &amp; port for device" menu entry. Also, my problem is similar to <a href="https://github.com/Microsoft/vscode-react-native/issues/324" rel="nofollow noreferrer">this issue</a>.</p>
