I am getting below Error when Laravel 5.4 app was deployed on Heroku Platform.
Key path "file:///app/storage/oauth-private.key" does not exist or is not readable
This is because I have installed passport package which requires private keys and which are stored on Storage folder of Laravel App.
I can simply remove this line /storage/*.key
from .gitignore fo fix the issue
But I prefer a permanent and safe solution. How can I put private keys in heroku safely.
