Hello. I have a simple setup of one root module calling one local module and two environments.

./terragrunt.hcl
./env1/terragrunt.hcl
./env2/terragrutn.hcl

env1 works fine with run-all. env2 plan always returns Error: Backend initialization required, please run "terraform init" even after running run-all init successfully. Even after removing .terraform.lock.hcl and .terragrunt-cache and running run-all init successfully. I'm using terragrunt 0.46.3 and terraform 1.4.6. What might the problem be?

$ cat terragrunt.hcl
terraform {
  before_hook "before_hook" {
    commands = ["apply", "plan", "validate"]
    execute  = ["tflint", "--minimum-failure-severity=error", "--config", "${get_path_to_repo_root()}/.tflint.hcl"]
  }
}

generate "provider" {
  path      = "provider.tf"
  if_exists = "overwrite"
  contents  = <<EOF
provider "azurerm" {
  features {}
  subscription_id = "xxxxxxxxx"
}
EOF
}

remote_state {
  backend      = "s3"
  disable_init = true # Bucket is managed by another terraform root-module
  # disable_dependency_optimization = true
  config = {
    bucket         = "prod-azure-ece01-tf-state"
    dynamodb_table = "prod-azure-ece01-tf-state"
    region         = "eu-west-1"
    role_arn       = "arn:aws:iam::xxxxxxxxx:role/OperatorAccess"
    encrypt        = true
    profile        = "terraform"
    key            = "${path_relative_to_include()}"
    s3_bucket_tags = {
      owner      = "sre"
      maintainer = "terraform"
      purpose    = "ece environments"
      repo       = "https://github.com/xxxxxxx"
    }
  }
  generate = {
    path      = "backend.tf"
    if_exists = "overwrite"
  }
}

cat env2/terragrunt.hcl
include "dev" {
  path = find_in_parent_folders()
}

terraform {
  source = "../..//root-modules/ece_env"
}

inputs = {
 ....
}

From this bug gruntwork-io/terragrunt#1422 it seems that disable_init means both don't generate the backend bucket and don't generate the state file in the bucket. Indeed if I set this to false (the default) I don't have the OP problem. I don't feel this setting should do what it does.

Hi @neilhwatson
Prior to running run-all init please enable terraform trace flag and attach the output here.
Thanks.

To enable logging:
Linux/Mac terminal
export TF_LOG="TRACE"

Windows PowerShell terminal
$Env:TF_LOG="TRACE"

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

This bit might be something:

Understood. Glad to see you have a workaround. I see you already upvoted terragrunt's issue 1422. Thanks.
