bug: Vault Secret Engine Issue LUA Trust Certificates

[GrayHatLabs]

Current Behavior

I am running Api Six in stand-alone mode and want to use Vault for secret management.

I am using the Docker images, and I keep getting this error. I don't know how to add certificates to the trust.

global_rules:
-
id: 1
plugins:
key-auth:
header: "Authorization"

routes:
- id: "test_route"
uri: "/test"
plugins:
key-auth: {}
upstream:
type: roundrobin
scheme: "https"
nodes:
"postb.in:443": 1

consumers:
- username: nemus_dupper
plugins:
key-auth:
key: $secret://vault/1/nemus_dupper/auth-key

secrets:
- id: vault/1
ssl_verify: false
prefix: apisix
token: hvs.asdfasdfasdfasdf
uri: https://vault.mydomain.com:8200/

Expected Behavior

I would like it to call the vault server I've specified in the config.
