I am trying to deploy a Django application to Heroku. When I followed the documentation and tried the command git push heroku master, I am getting an error: failed to push some refs to 'https://git.heroku.com/sleepy-eyrie-25993.git'. I searched online and tried to use git pull. But it didn't work. I also tried using git push -f heroku master, but still getting the same error. Is there any other way to do it? I followed this doc
https://devcenter.heroku.com/articles/python-support.
Tried using the heroku dashboard, but it is giving the same error
Building on the Heroku-18 stack ! No default language could be detected for this app. HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically. See https://devcenter.heroku.com/articles/buildpacks ! Push failed
