It seems that the version of the key/value engine can not always be detected for Hashicorp Vault. In certain cases, it is required to configure the `VAULT_BACKEND` (or `vaultBackend`) option so that a successful connection to the service can be made. The `kv-v2` is the current default for development deployments of Hashicorp Vault (what we use for automated testing). Production deployments default to version 1 for now.
