I am trying to deploy a project to heroku and I am getting this error:-
Counting objects: 70, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (64/64), done.

remote: HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically.
remote: See https://devcenter.heroku.com/articles/buildpacks

If you go to my github project, I have everything required for the heroku project including runtime.txt
file but still I am getting this error. I tried changing different python versions supported by Heroku but still same error. Could anyone help me out ?
If I add a buildpack then I am getting the following error
Counting objects: 70, done.

Not sure where I am going wrong ?
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. We look for signatures for each language we support (like a pom. xml file or package. json file).
Open the file using a text editor and add any dependencies needed such as numpy in order to run your project as when you deploy to Heroku the “pip” install command will be running to make sure all dependencies are present in order to run the script. 3. git add .
A possible solution to this problem can be specifying the buildpack during app creation like :
$ heroku create myapp --buildpack heroku/python
or after app creation like:
$ heroku buildpacks:set heroku/python
Refer Docs : Heroku Docs
The other problem I figured was that I had unnecessary package.json
and other files in my django project. I solved it by removing unnecessary files from my app directory.
Since these files were obstructing the automatic detection of buildpack.
Another reason of failed detection could be wrong folder structure of your app. The Procfile
and other heroku files should be right at the start of the git directory otherwise your app won't get detected.
