Data source vault_identity_entity fetching entity name under aliases

Hi All,
I am trying to fetch all the entity names using data source vault_identity_entity, however unable to fetch the name of entity located under aliases.

Sample code:
data “vault_identity_group” “group” {
group_name = “vaultadmin”
data “vault_identity_entity” “entity” {
for_each = toset(
entity_id = each.value
data “null_data_source” “values” {
for_each = data.vault_identity_entity.entity
inputs = {
ssh_user_details = lookup(jsondecode(data.vault_identity_entity.entity[each.key].data_json),“name”,{})

Above scripts returns entity id again. Any suggestions to retrieve the name field under aliases, which has users email id.
