Reference before assignment in login

[hughsaunders]

Summary

When logging into conjur using a self signed cert I encountered a reference before assignment error.

Steps to Reproduce

1. Install cyberark-conjur-cli v7.1.0 via DMG on macOS 12.3.1
2. Initialise the cli:

   
   $ conjur init -u https://localhost -a conjur -s
   Using self-signed certificates is not recommended and could lead to exposure of sensitive data.
   Continue? yes/no (Default: no): yes

The Conjur server's certificate SHA-1 fingerprint is: 18:22:53:16:6E:6C:B4:52:B4:4F:D3:0E:5E:16:74:34:C8:AF:FF:76

To verify this certificate, we recommend running the following command on the Conjur server: openssl x509 -fingerprint -noout -in ~conjur/etc/ssl/conjur.pem

Trust this certificate? yes/no (Default: no): yes File /Users/hugh.saunders/conjur-server.pem exists. Overwrite? yes/no (Default: yes): yes Certificate written to /Users/hugh.saunders/conjur-server.pem

File /Users/hugh.saunders/.conjurrc exists. Overwrite? yes/no (Default: yes): yes Configuration written to /Users/hugh.saunders/.conjurrc

Successfully initialized the Conjur CLI To start using the Conjur CLI, log in to the Conjur server by running conjur login

3. Login:
