panic with Vault kv-v2 secret engine

[apowers]

When attempting to read a key from Vault using the kv-v2 secret engine, envconsul panics with map[string]interface {}, not string

Envconsul version

$>envconsul -v
envconsul v0.7.3 (daa2947)

Configuration

vault {
    address = "https://vault.local.domain"
    token   = "<redacted>"

    ssl {
        enabled = true
        verify = false
    }
}
secret {
    no_prefix = true
}

Command

envconsul -config config.hcl -log-level debug -secret secrets/data/test env

Debug output

2018/05/29 17:24:02.832503 [DEBUG] (runner) setting secrets_data_test_data=map["database__password": "<redacted>"]from vault.read(secrets/data/test)
panic: interface conversion: interface {} is map[string]interface {}, not string

        /go/src/github.com/hashicorp/envconsul/cli.go:119 +0x499

Expected behavior

Should set environment data.

Actual behavior

Panic

envconsul -config config.hcl -log-level debug -secret secrets/test env results in "no secret exists at secrets/test"

Data can be read using curl.
curl --header "X-Vault-Token: <redacted>" --request GET --data @payload.json --insecure https://vault.local.domain/v1/secrets/data/test

Steps to reproduce

1. Create a secret engine using kv-v2
2. Create some data
3. Attempt to read the data with envconsul

Is there an update on this?
We have enabled versioned backend. I am getting map[string]interface {}, not string error when using envconsul.

I've opened #186 that should address this and support both kv versions
