I had to install a buildpack on the heroku website for my app. I followed the answer to this question: Error while excuting chrome without headless on heroku
It says that "on the next deploy, your app will also install the dependencies that your module needs to run."
I tried to redeploy my code without any changes to it, using:
git add .
git commit -am "Changes"
git push heroku master
But because i don't have any changes to my code it will not let me. So can i rerun the application on the existing commit?
