Heroku error: “Permission denied (public key)”

Question

I keep getting this error. I am using Mac. I generated a key and added it to heroku using

heroku config:add key=\"ssh-rsa blahblah=me@me.com\"

Answer 1

the solution above did not work for me as I did not have any keys generated in my ~/.ssh folder.

My solution was to simply type heroku keys:add

The output in terminal was:

Could not find an existing public key.
