UPDATE
I know now (from running heroku run bash and ls -la) that indeed the config directory is missing after deployment to heroku. It is however present in local repository.
.gitignore
/.bundle
# Ignore the default SQLite database.
/db/*.sqlite3
# Ignore all logfiles and tempfiles.
/log/*.log
*.log
/tmp
After I push my application to heroku I get a LoadError for /app/config/environment, which has not happened in previous releases.
No changes to config.ru were made.
The file config/environment.rb is present.
I tried a rollback, but couldn't because the previous release has a different add-on set.
How can I solve this error?

I have contacted heroku on a similar issue for my app, we discovered that removing the file .slugignore which is beside file .gitignore fixed the problem.
May be its the same case at your side, you can see my question here: why config folder is not pushed?
and see my answer to my question.
I hope this will help
