terraform-provider-azurerm: Data Source for custom role definition using azurerm_role_definition is not working

Terraform (and AzureRM Provider) Version

Azure RM 2.63.0

Affected Resource(s)

azurerm_role_definition

1. Create a custom role definition ‘xyz_custom_01’ via terraform using resource block of azurerm_role_definition
2. Use data block as below to retrieve the output of custom role Definition deployed in Step1

   data "azurerm_role_definition" "all_role_definitions2" {
     name     = "xyz_custom_01"
     # scope    = data.azurerm_subscription.primary.id
     provider = azurerm.Subscription
   }

Tried using with and without scope parameter. I get error as-

Error: Error loading Role Definition List: could not find role 'xyz_custom_01'

  on MAIN_01_IAM.tf line 10, in data "azurerm_role_definition" "all_role_definitions2":
  10: data "azurerm_role_definition" "all_role_definitions2" {

But the same when I used role_definition_id and fetched the name of custom role definition, it worked. Looks like a bug in data source.
