title: Heroku app page not found
body: <p>I deployed a rails app on Heroku. Everything was working fine. I pushed the code to Heroku master, and everything worked as expected. I also ran <code>Heroku run rails db:migrate</code>. No errors were thrown. I can even run the <code>Heroku run rails console</code>, and create objects, no problem. However, It does tell me that I have to type in User.connection, (Users are the only models I have in the app right now). When I type <code>Heroku config</code> I get expected output. Everything seems perfect. But, when I open the app, it says that the page is not found: </p>
  
  <pre><code>No webpage was found for the web address: https://my-api.herokuapp.com/
  </code></pre>
  
  <p>It's probably worth mentioning that It's a rails API, therefore, there are no views, and no root page. But despite that, I still don't get any responses when I make API calls with Postman. I simply get a 404 response. I would at least imagine that HTTP requests would work, but they don't. Any idea why?</p>
  
  <p>Upon loading the app the logs say</p>
  
  <pre><code>ActionController::RoutingError (No route matches [GET] "/"):
  </code></pre>
  
  <p>does mean there is no root route? I thought for an API, there didn't need to be one?</p>
