First of all, the creative formatting of the code in your post makes it difficult to read. Just a minor note that I wanted to share for the sake of yourself and everyone else in the future. Second, and most important, Gruntwork does not maintain modules within `github.com/terraform-aws-modules`. We suggest you ask about this issue over there. (Be sure to format correctly!) Thirdly, as we maintain Terragrunt, `terragrunt run-all plan` is not a reliable command in all cases. Please see the [documentation](https://terragrunt.gruntwork.io/docs/features/execute-terraform-commands-on-multiple-modules-at-once/#the-run-all-command) on `run-all`, especially the section on `plan`.
