Hashicorp Vault cluster terraform problem

Terraform
1

Hi,

I am using official hashicorp git repo template for Terraform which I am doing in my gitlab using CI pipeline. So far the furthest i came with the aws provider version 4.67 (from version 5+ i am getting tags error).

Validation phase is successful, but i am stopped at the subnets part (i already replaced aws_subnet_ids with the new aws_subnets version) but I keep getting null results for subnets. I have checked, i get VPC data successfully.

*i am using a new fresh region, so all network data is default

My code in main.tf:

data "aws_vpc" "default" {
  default = var.vpc_id == null ? true : false
  id      = var.vpc_id
}


data "aws_subnets" "default" {
  filter {
    name   = "vpc-id"
    values = [var.vpc_id]
  }
}

data "aws_subnet" "default" {
  for_each = data.aws_subnets.default.ids
  id       = each.value
}

output "subnet_cidr_blocks" {
  value = [for s in data.aws_subnet.default : s.cidr_block]
}

Error i keep getting:

│ Error: Null value found in list
│ 
│   with data.aws_subnets.default,
│   on main.tf line 149, in data "aws_subnets" "default":
│  149: data "aws_subnets" "default" {
│ 
│ Null values are not allowed for this attribute value.

I have made some simple terraform configs (mostly for my ESXi VM creation with cloud-config), but this is whole new level :slight_smile:

If anyone please has any idea what am I doing wrong.

Works with this:

data "aws_vpc" "default" {
  default = var.vpc_id == null ? true : false
  id      = var.vpc_id
}


data "aws_subnets" "default" {
  filter {
    name   = "vpc-id"
    values = [data.aws_vpc.default.id]
  }
}


data "aws_subnet" "default" {
  for_each = toset(data.aws_subnets.default.ids)
  id       = each.value
}

*Was having problem with this for many hours
