Push rejected by Heroku for the static file collection reason - django

Question

When I'm trying to deploy a Django app to Heroku, encounter the identical problem as python - Collectstatic error while deploying Django app to Heroku - Stack Overflow
it starts to build, download and installs everything, but that's what I get when it comes to collecting static files:
$ git push heroku master
Counting objects: 5375, done.
Total 5375 (delta 1092), reused 0 (delta 0)
remote: Compressing source files... done.
remote: Building source:
remote:
remote: -----> Python app detected
remote: -----> Installing requirements with pip
remote:
...
remote:
remote: ! Error while running '$ python manage.py collectstatic --noinput'.
remote: See traceback above for details.
remote:
remote: You may need to update application code to resolve this error.
remote: Or, you can disable collectstatic for this application:
remote:
remote: $ heroku config:set DISABLE_COLLECTSTATIC=1
remote:
remote: https://devcenter.heroku.com/articles/django-assets
remote: ! Push rejected, failed to compile Python app.
remote:
remote: ! Push failed
remote: Verifying deploy....
remote:
remote: ! Push rejected to fierce-cove-94300.
remote:
To https://git.heroku.com/fierce-cove-94300.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/fierce-cove-94300.git'
I tried all its answers, but not helps.
Additional I tried Django and Static Assets | Heroku Dev Center to configure the setting and install whitenoise and commit changes.
The problem is not solved.

Disable auto collectstatic:
heroku config:set DISABLE_COLLECTSTATIC=1
Then push your project to heroku. After the deploy is done, manually collectstatic as below:
heroku run python manage.py collectstatic
If you still get errors, your static files config is probably the reason. Try making it simple, remove whitenoise and use a s3 bucket for example.
