Challenges in Configuring terragrunt

I am trying to get the backend.tf created for all sub-folders included in the current project. I have installed terragrunt on my local system

   $ which terragrunt
   /usr/local/bin/terragrunt
   $ terragrunt -version
   terragrunt version v0.28.18

Here is my terragrunt.hcl from my parent folder

 $ cat  /user_folder/user-x/terragrunt.hcl
remote_state {
  backend  = "gcs"
  generate = {
    path = "backend.tf"
    if_exists = "overwrite_terragrunt"
  }
  config = {
    bucket  = "terraform-bucket"
    prefix = "${path_relative_to_include()}/user_folder/user-x/terraform.tfstate"
  }
}

In my sub-folder /user_folder/user-x/permissions/, I have terragrunt.hcl

$ cat  /user_folder/user-x/permissions/terragrunt.hcl
include {
  path = find_in_parent_folders()
}

Also I have exported GOOGLE_APPLICATION_CREDENTIALS with the appropriate JSON.

Now when I execute

$ terragrunt plan --terragrunt-log-level debug --terragrunt-debug
                                                                                                    DEBU[0000] Did not find any locals block: skipping evaluation.

DEBU[0000] The file path /mylocalpc/git_test_repo/user-x/backend.tf already exists, but was a previously generated file by terragrunt. Since if_exists for code generation is set to "overwrite_terragrunt", regenerating file.

ERRO[0003] Missing required GCS remote state configuration project
ERRO[0003] Unable to determine underlying exit code, so Terragrunt will exit with error code 1

And the GCS bucket terraform-bucket does exists. Unsure what I'm missing here... looking for kind help

In my case, I had the cloud storage created. So had to specify skip_bucket_creation to true. Check out terragrunt doc for details (search for skip_bucket_creation).

remote_state {
  backend = "gcs"  
  generate = {
    path      = "backend.tf"
    if_exists = "overwrite_terragrunt"
  }
  config = {
    bucket  = "some-bucket"
    prefix  = "some-prefix"
    skip_bucket_creation = true
  }
}

Because of this:

  ERRO[0003] Missing required GCS remote state configuration project

I think you need to run these before you run terragrunt?

  gcloud config set project <your project>
  gcloud auth application-default login
