Why does my app "fail to detect" a buildpack?


When you push your code to Heroku, the build fails with a message like "Failed to detect app matching no buildpack" or "Failed to detect app matching Node.js."


This error message means that Heroku was unable to automatically detect the type of app you're trying to deploy: Ruby, Node, Python, PHP, Java, etc.

Please ensure you complete the language-specific setup as noted in our DevCenter Documentation
