Error when submitting a new request

Using ssh-cert-authority version 2.0.0-6-g59dae40 built with go version go1.17 linux/amd64 when I run `ssh-cert-authority request -e production -r "Testing" -p vendion -c /home/vendion/.config/ssh_ca/requester_config.json` it errors out with the following error:

```
Dial failed: dial unix: missing address
```

My requester_config.json file is as follows

```json
{
"production": {
"PublicKeyPath": "/home/vendion/.ssh/id_ed25519_uf.pub",
"SignerUrl": "https://ssh-ca.utiliflex.com/"
}
}
```

This file was created by `ssh-cert-authority generate-config --url 'https://ssh-ca.utiliflex.com'` so I don't know what address could be missing that it is complaining about.
