title: Metro Builder: SyntaxError: Unexpected token = after upgrading to React Native 0.65.1
body: <p>Today <a href="https://react-native-community.github.io/upgrade-helper/?from=0.64.2&amp;to=0.65.1" rel="noreferrer">I updated to React Native Version 0.65.1</a>.
  After that I was unable to Start the Metro Server</p>
  <p>I am now receiving following error message while building a Release .apk:</p>
  <pre><code>    node_modules/metro/src/Server.js:350
    processRequest = (req, res, next) =&gt; {

  <p>This is the snippet from the Metro Server Node Module</p>
