title: How to delete AppEngine default service in the existing Google Cloud project with Firestore
body: <p>I've the existing Google Cloud project that was created by Firebase and use Firestore in this project. Decided to try AppEngine and run <a href="https://github.com/GoogleCloudPlatform/nodejs-getting-started/blob/master/1-hello-world/" rel="noreferrer">Hello World Example</a> in this project.</p>
  
  <p>Now I want to delete this newly deployed AppEngine Service, but there are 2 problems:</p>
  
  <p>1) Hello World Docs suggest to switch off the AppEngine. In this case Firestore is not working</p>
  
  <p>2) Can't delete this service from CLI/UI as this service was deployed as the default one</p>
  
  <pre><code> Issue deleting service: [default]
   The default service (module) cannot be deleted.
  </code></pre>
  
  <p>Is there a way to delete this service from the project and keep Firebase Firestore?</p>
