I have the same issue - any suggestions how to resolve..?

[yashraj-unthinkable]

@fabricesemti80 you can use terragrunt mock outputs https://terragrunt.gruntwork.io/docs/features/execute-terraform-commands-on-multiple-modules-at-once/#unapplied-dependency-and-mock-outputs

Can you a bit elaborate how mock outputs can help with this case? Judging by the error, Terragrunt can't find configurations,. I'm not quite understand how mocking outputs are related to the find_in_parent_folders behaviour.

This appears to still be an issue, and it seems using the structure in this repo doesn't work with Terragrunt.

I'm using:

❯ terragrunt --version                                
terragrunt version 0.66.9

Here is my directory layout:

~/tmp/example on ☁️  materer-dev (us-east-1) 
❯ tree                   
.
├── dev
│   ├── account.hcl
│   └── key
│       └── terragrunt.hcl
├── prod
│   ├── account.hcl
│   └── key
│       └── terragrunt.hcl
└── terragrunt.hcl

5 directories, 5 files

And the files:

File: terragrunt.hcl
Path: ./terragrunt.hcl

Contents:
locals {
  account_info = read_terragrunt_config(find_in_parent_folders("account.hcl"))
  profile = local.account_info.locals.profile
}

generate "provider" {
    path = "provider.tf"
    if_exists = "overwrite_terragrunt"
    contents = <<EOF
provider "aws" {
    region = "us-east-1"
    profile = "${local.profile}"
}
EOF
}

And the error I get:
