title: Kotlin/JS, Gradle Plugin : Unable to load '@webpack-cli/serve' command
body: <p>I was doing the tutorial for React Kotlin and couldnt even finish the setup step because the server does not start.</p>
  <p>The code is unchanged : <a href="https://github.com/kotlin-hands-on/web-app-react-kotlin-js-gradle" rel="noreferrer">https://github.com/kotlin-hands-on/web-app-react-kotlin-js-gradle</a></p>
  <p>Stacktrace:</p>
  <pre><code>[webpack-cli] Unable to load '@webpack-cli/serve' command
  [webpack-cli] TypeError: options.forEach is not a function
  [webpack-cli] TypeError: options.forEach is not a function
  </code></pre>
  <p>I saw this issue : <a href="https://github.com/webpack/webpack-cli/issues/2990" rel="noreferrer">https://github.com/webpack/webpack-cli/issues/2990</a> but I'm unable to implement the fix proposed (change the webpack-cli version and remove the webpack-cli/serve from yarn.lock) because I can't find how to change these on the kotlin js gradle plugin.</p>
  <p>Even simple browser application from intelliJ is broken with the same error.</p>
