title: HEROKU: ps:scale web=1 no such process type web defined in Procfile
body: <p>I have seen very similar posts, that however did not help me to find a solution to my problem. </p>
  
  <p>I am following step by step the guide to upload a project on heroku. </p>
  
  <p>However when I type the command: </p>
  
  <pre><code>ps:scale web=1 
  </code></pre>
  
  <p>The result is: </p>
  
  <pre><code>no such process type web defined in Procfile
  </code></pre>
  
  <p>I have created a file "Procfile" being careful at the capitalization. but nothing. </p>
  
  <p>What else can I do to solve this problem??</p>
  
  <p>Thanks in advance. </p>
