Hey all,  
Want to be able to get remote state output ( instance ids )and use that in a custom module that creates an ALB .  
Existing code works - I can add multiple members with multiple data blocks defined

> data “terraform\_remote\_state” “mydata” {  
> backend = “s3”  
> config = {  
> region = var.region  
> bucket = “abc-{var.region}-{xxx}-tf-states”  
> key = “env:/${var.environment}-abc/terraform.tfstate”  
> }  
> }
> 
> module “mymodule” {
> 
> members = [  
> data.terraform\_remote\_state.mydata.outputs.instance-id
> 
> ]
> 
> }

Refactored code throws an error on plan - This object does not have an attribute named instance-id .

> locals {  
> members = {  
> default = [“env:/{var.environment}-xxx/terraform.tfstate", "env:/{var.environment}-xxy/terraform.tfstate”,]  
> dev = [“env:/{var.environment}-xxx/terraform.tfstate", "env:/{var.env2}-xxc/terraform.tfstate”]
> 
> }  
> }
> 
> data “terraform\_remote\_state” “mydata” {  
> for\_each = lookup(local.members, var.env2, “default”)  
> backend = “s3”  
> config = {  
> region = var.region  
> bucket = “abc-{var.region}-{xxx}-tf-states”  
> key = each.value  
> }  
> }
> 
> module “mymodule” {
> 
> members = [for outputs in data.terraform\_remote\_state.mydata : outputs.instance-id]
> 
> }

I messed around with it and got it to work - just posting here if it helps. Since the custom module accepts a list for members - I used this

members = tolist([for outputs,state in data.terraform\_remote\_state.mydata : state.outputs.instance-id])
