Integration with molecule test 'object has no attribute 'code'

[snoby]

Hi, I'm certain that I'm doing something wrong... I'm using Molecule V2 to run on one of my roles inside my playbook. This particular role calls into vault to obtain a value. My issue is that I'm getting a cryptic python error and I'm stuck on where to debug the issue.
In molecule you can create a config file where you can customize certain configs such as a mock up ansible.cfg for example my molecule.yml file looks like this:

---
dependency:
  name: galaxy
driver:
  name: docker
lint:
  name: yamllint
platforms:
  - name: instance
    image: centos:7
provisioner:
  name: ansible
  config_options:
    defaults:
      lookup_plugins : ../../../../../lookup_plugins
  lint:
    name: ansible-lint
scenario:
  name: default
verifier:
  name: testinfra
  lint:
    name: flake8

Now if I do not set the lookup_plugin line above then I get an error that the playbook can't find vault... so I know ansible is able to find the plugin, however I'm getting this error when I run the converge command which is equivalent to running the playbook on just this role:

  TASK [common : Obtain from vault the private ssh key for user ansible] *********
    task path: /Users/snoby/work/Official/tropo-ops-proxy-ansible/roles/common/tasks/main.yml:36
    fatal: [instance]: FAILED! => {
        "msg": "An unhandled exception occurred while running the lookup plugin 'vault'. Error was a <type 'exceptions.AttributeError'>, original message: 'exceptions.AttributeError' object has no attribute 'code'"
    }

It seems like something can't dereference in the path where the code is for the plugin. Any suggestions?

One additional factoid which may simplify the test here as well. I tried to just run the whole playbook with the vault lookup plugin and I was returned with the same result of:

TASK [common : Obtain from vault the private ssh key for user ansible] *********************************************************************
fatal: [proxy1b.int.tropo.com]: FAILED! => {"msg": "An unhandled exception occurred while running the lookup plugin 'vault'. Error was a <type 'exceptions.AttributeError'>, original message: 'exceptions.AttributeError' object has no attribute 'code'"}

PLAY RECAP *********************************************************************************************************************************

So this has nothing to do with molecule. I install the plugin by making it a git submodule.

decided to go with hashivault as it works right out of the box...
