title: Heroku deployment error: The requested API endpoint was not found
body: <p>I have the worked app (Availible here <a href="https://tandtpartners.herokuapp.com" rel="noreferrer">tandtpartners.herokuapp.com</a>)<br>
  But I've got the <br> <code>remote: !       The requested API endpoint was not found. Are you using the right HTTP verb (i.e. GET vs. POST), and did you specify your intended version with the Accept header?</code><br> error while trying to deploy the app again.
  <br>
  Even when I cloned this app to another folder and added some <code>!</code> to <code>index.html</code>, I received the same error.</p>
