  <p>I even visited Heroku's link <a href="https://devcenter.heroku.com/articles/buildpacks#detection-failure" rel="noreferrer">https://devcenter.heroku.com/articles/buildpacks#detection-failure</a>  and tried to implement every method that they have mentioned but nothing seems to be working for me.</p>
  
  <p>Can someone please assist?</p>
