Cloning private repo fails

[bradleyhodges]

sudo systemctl status caddy.service -l produces the following error:

May 08 06:55:02 app-1 systemd[1]: Started Caddy HTTP/2 web server.
May 08 06:55:02 app-1 caddy[23804]: Activating privacy features... done.
May 08 06:55:02 app-1 caddy[23804]: 2018/05/08 06:55:02 cannot git clone into /var/www, directory not empty

May 08 06:55:02 app-1 systemd[1]: caddy.service: Failed with result 'exit-code'.

The /var/www directory is completely empty, but every time I start caddy, it adds a ".ssh" directory to it. Any ideas?

Caddy file is:

git { repo https://github.com/username/repo.git branch master key /ssh/id_rsa hook /servicePush password }

When using private key, use ssh format. i.e. git@github.com:username/repo

Same issue here.
I'm specifying my key as being in /root/.ssh but caddy will still try and use /var/www/.ssh and fail.

My repo address is in format git@github.com:username/repo
