How to retrieve details out of a data source built upon multiple resources having dot notation

Hello

   I have created a data source based on a multi-instance resource.  

sample code below.

data "vra_cloud_account_vsphere" "this" {
  for_each = {
    for account in local.fa : "${account.name}.${account.hostname}" => account
  }
  name = each.value.name
}

I am trying to get the id of the data source using name but couldn’t achieve to get it while there is a dot notation in the attribute. Is there a way to handle this while I want to keep the dot notation in the attribute.

here is the output when I try data.vra_cloud_account_vsphere.this in terraform console. I did massage some data below.

{
    "ac1.prod.domain.com.ac1.prod.domain.com" = {
      "associated_cloud_account_ids" = tolist([])
      "created_at" = "2021-10-05"
      "custom_properties" = tomap({
        "acceptSelfSignedCertificate" = "true"
        "buildNumber" = "18485185"
      })
      "dcid" = ""
      "description" = "ac1 Hosting Production vCenter"
      "enabled_region_ids" = tolist([
        "Datacenter:datacenter-26",
        "Datacenter:datacenter-253",
        "Datacenter:datacenter-21",
        "Datacenter:datacenter-1014",
      ])
      "hostname" = "ac1.prod.domain.com"
      "id" = "37840775-7761-44b9-b4ca-cf68008e25ff"
      "name" = "ac1.prod.domain.com"
      "org_id" = "0d24d0a8-ef40-4e48-8fb1-bd737d423935"
      "owner" = ""
      "tags" = toset([])
      "updated_at" = "2021-10-07"
      "username" = tostring(null)
    }
    "ac2.prod.domain.com.ac2.prod.domain.com" = {
      "associated_cloud_account_ids" = tolist([])
      "created_at" = "2021-10-05"
      "custom_properties" = tomap({
        "acceptSelfSignedCertificate" = "true"
        "buildNumber" = "18485185"
      })
      "dcid" = ""
      "description" = "ac2 Hosting Production vCenter"
      "enabled_region_ids" = tolist([
        "Datacenter:datacenter-21",
        "Datacenter:datacenter-26",
      ])
      "hostname" = "ac2.prod.domain.com"
      "id" = "a985552f-97c6-4d06-b4d8-b9f031b89caa"
      "name" = "ac2.prod.domain.com"
      "org_id" = "0d24d0a8-ef40-4e48-8fb1-bd737d423935"
      "owner" = ""
      "tags" = toset([])
      "updated_at" = "2021-10-07"
      "username" = tostring(null)
    }
  }

here is error I get when I run data.vra_cloud_account_vsphere.this["ac1.prod.domain.com.ac1.prod.domain.com"] from tf console.

Error: Invalid index

  on <console-input> line 1:

    |----------------
    | data.vra_cloud_account_vsphere.name_map is object with 2 attributes

The given key does not identify an element in this collection value.

looks like there wasn’t a direct option. Was able to solve it by looping through them and getting into locals.

  vcav_name_id = flatten([for vcav in vra_cloud_account_vsphere.this :
    {
      name = vcav.hostname
      id  = vcav.id
    }
  ])
