Ansible asking for ssh key passphrase for key that does not have one

问题

I generated an rsa_id ssh key, and used ssh-copy-id on my own account on localhost, just to test running Ansible against localhost with ssh.

I did not use a passphrase. However, when running ansible against localhost, I'm prompted with:

Enter passphrase for key '/home/username/.ssh/id_rsa.pub':
