heroku push error: “rake assets:precompile rake aborted!”

Question

I'm trying to push my changes to Heroku with the following command: git push heroku master

When running the rake assets:precompile, I get the following error(s):

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       NameError: undefined local variable or method `fkalkhalidi' for #<Pinteresting::Application:0x007f48fd2d6fc0>

What's inside the file config/environments/production.rb at line 80?

Search your code, specifically in the production.rb file. It's likely there is a fkalkhalidi string somewhere that is causing the error.
