Terraform v0.15.4
on windows_amd64
+ provider registry.terraform.io/hashicorp/azurerm v2.60.0

Affected Resource(s)

• azurerm_network_service_tags

Terraform Configuration Files

data "azurerm_network_service_tags" "frontdoor" {
  location        = azurerm_resource_group.main.location
  service         = "AzureFrontDoor.Backend"
  location_filter = " "
}

Debug Output

Panic Output

Expected Behaviour

Getting all IP's for AzureFrontDoor.Backend

Actual Behaviour

Getting error:

Error: specified service tag AzureFrontDoor.Backend not found globally

isServiceTagOf function in https://github.com/terraform-providers/terraform-provider-azurerm/blob/1aaa389743ff39c281367a8ad85b7b94540b4206/azurerm/internal/services/network/network_service_tags_data_source.go#L107 that match service tag to returned value from Azure makes the assumtion that name does not contain any dot, and if it does the last part is region. So for AzureFrontDoor.Backend it is unable to match the name to service.

Steps to Reproduce

1. terraform apply

@tesharp - I ran into this same issue today and agree there is a bug. I did however find a workaround for my use case.

data "azurerm_network_service_tags" "service_tags" {
  location        = var.region
  service         = "AzureFrontDoor"
}

Omitting the Backend from the full service names appears to match on the first returned list of the AzureFrontDoor service names which happens to be Backend right now.
