Missing Environment Variables

[tide-jamiegwatkin]

We're testing terragrunt-atlantis-config with the intention of using it with Atlantis but am having a strange issue where ENV vars are not being found.

When running terragrunt-atlantis-config generate --output atlantis.yaml --autoplan --parallel --root core/eks_main/, terragrunt-atlantis-config fails to find any environment variable that has been defined in terragrunt.hcl.

The error outputted is:

[root@ terraform]$ terragrunt-atlantis-config generate --output atlantis.yaml --autoplan --parallel --root core/eks_main/

ERRO[0000]    4:   application       = get_env("OP_TF_APP") 

When eching the env vars in the shell I'm able to see them all e.g:

[root@ terraform]$ env | grep OP_TF_ENV
OP_TF_ENV=test

The locals defined in /terraform/core/terragrunt.hcl look like this:

locals {
  ...
  environment       = get_env("OP_TF_ENV")
  application       = get_env("OP_TF_APP")
  country           = get_env("OP_TF_COUNTRY")
  root_folder       = get_env("OP_TF_ROOT_DIR")
  production_access = get_env("OP_PRODUCTION_ACCESS", "yes")
...
}

core/eks_main/terragrunt.hcl looks like:

terraform {
  source = ".//."
}

include "root" {
  path = find_in_parent_folders()
}

dependencies {
  paths = [
    "../other_resources"
  ]
}

Am I doing something wrong with this configuration?
