Terraform Version

Terraform v1.9.8 on darwin_arm64

Client Version

Neovim (builtin lsp)

Terraform Configuration

locals {

  # This works fine
  # service_accounts = [
  #   "serviceAccount:[email protected]",
  # ]

  # but this doesn't:
  service_accounts = [for sa in [
    "[email protected]",
  ] : "serviceAccount:${sa}"]

  subscribers = local.service_accounts
}

provider "null" {}

resource "null_resource" "example" {}

Steps to Reproduce

1. Save the above config in a file
2. Run terraform init
3. See the error in your editor

Expected Behavior

No error being reported

Actual Behavior

An error is reported at the line including subscribers = local.service_accounts. The error message is:
Terraform: No declaration found for "local.service_accounts"

Additionally, since the local variable is not identified, additional functionalities such as go to definitions doesn't work for it.

Well I tracked this down to

terraform-ls/internal/features/modules/decoder/validations/unreferenced_origin.go

Line 58 in 0ec634c

_, ok = pathCtx.ReferenceTargets.Match(localOrigin)

Match function fails to match the local variable, even though it is in the reference targets. Seems that the issue is on hcl-lang module. I may spend more time on this tomorrow to find out where the issue is.
