A Problem with App Connector Group Attributes

[afellows142]

I just ran into a problem with the "id" attribute for a zpa_app_connector_group resource, and any help would be appreciated. I'm using App Connector Group and Server Group modules that I made in the same config file, which looks like this

  source    = "../tf-zscaler-app-connector-group-module/"
  enabled   = true
  latitude  = ""
  location  = ""
  longitude = ""
  name      = "app-connector-group_aws-xoominfoaws-production"

}

module "sg_aws-xoominfoaws-production" {
  source = "../tf-zscaler-server-group-module/"
  name   = "server-group_aws-xoominfoaws-production"
  acg_id = [module.acg_aws-xoominfoaws-production.id]
}

The acg_id is what I named the variable for the id for the App_Connector_Group, as seen here:

resource "zpa_server_group" "main" {
  name = var.name
  app_connector_groups {
    id = var.acg_id
  }
}

When I run a plan, the following error gets thrown and I can't tell why.

│
│   on acg_sg_test.tf line 15, in module "sg_aws-xoominfoaws-production":
│   15:   acg_id = [module.acg_aws-xoominfoaws-production.id]
│     ├────────────────
│     │ module.acg_aws-xoominfoaws-production is a object, known only after apply
│
│ This object does not have an attribute named "id".

Hi @afellows142 the app_connector_groups parameter is supposed to be a list of IDs as per the example below
https://github.com/zscaler/terraform-provider-zpa/tree/master/examples/zpa_server_group

// Create Server Group - Dynamic Discovery "True"
resource "zpa_server_group" "example" {
  name = "Example"
  description = "Example"
  enabled = true
  dynamic_discovery = true
  app_connector_groups {
    id = [data.zpa_app_connector_group.example.id]
  }
}

data "zpa_app_connector_group" "example" {
  name = "Example"
}

Thanks William. That actually wasn't my problem as I am passing it as a list

acg_id = [module.acg_aws-xoominfoaws-production.id]

The issue I had involved variable type. When you import resources to a state file, it imports them as string values which is why I had my variable type set as set(string). When attempting to create the server group through my module it wasn't inferring the string as a number. As soon as it was changed to set(number) it stopped having that error.
