@Paul Gale Ah right, my example was using the raw key as the environment variable so I can store it in GitHub secrets. If you just want to set the key path from an environment variable you need to drop the

key-data:

part, so it would look like:

ssh:
    host-key-check: false
    private-key:
      _plugin: env_var
      var: BOLT_SSH_PRIVATE_KEY_PATH
