The HCL looks like this:

data "aws_availability_zones" "available" {
}

data "aws_subnet" "private" {
  count             = var.subnet_count
  availability_zone = element(data.aws_availability_zones.available.names, count.index)

  tags = {
    Type = "private"
  }

  vpc_id = var.vpc_id
}

Hovering or navigating to usage/definition/declaration doesn’t work in most cases and simply reports that it cannot be found. It can find Data Source Type aws_availability_zones but hovering data.aws_availability_zones.available.names doesn’t do anything, neither does navigating to the declaration of data.aws_availability_zones.available.

Typing data.aws_availability_zones.av doesn’t yield autocompletion for data.aws_availability_zones.available either. It can do data.aws_avail and complete data.aws_availability_zones but beyond that it’s no use.

Other things it can’t find:

• symlinked HCL
• cross-module declarations
• submodule declarations
• Variables in TFVars

I’ve tried to find out if there is a list of known issues for finding usages/definitions but there doesn’t seem to be a detailed “it does not cross this type of boundary” list of things it tries to resolve.

Example of a variable that is filled by tfvars:

variables.tf

variable "namespace" {
  description = "The group this environment belongs to. Not optional."
}

environment.auto.tfvars

namespace = "hyperion"

Can’t navigate in either direction via references/declaration.
