Error: waiting for creation of MsSql Database - Terraform failure - terraform

Question

I have had to re-develop my pipeline for building out my infrastructure to use local agent pools and change Ubuntu code to windows (PowerShell code).
I am now in the position where I am building out my infrastructure and it failing on the most basic of tasks.
I have created my SQL Server and that seems to be OK. I have also got my logging system infra done OK too, but I am really struggling on building out a DB on my SQL Server.
At the most basic here is my code. Server build OK.
resource "azurerm_mssql_server" "main" {
name = local.sqlServerName
resource_group_name = local.resourceGroupName
location = var.location
version = "12.0"
minimum_tls_version = "1.2"
administrator_login = var.sql_administrator_login
administrator_login_password = var.sql_administrator_login_password
tags = var.tags
}
resource "azurerm_sql_active_directory_administrator" "main" {
server_name = azurerm_mssql_server.main.name
resource_group_name = local.resourceGroupName
login = local.sql_ad_login
tenant_id = data.azurerm_client_config.current.tenant_id
object_id = local.object_id
}
resource "azurerm_sql_firewall_rule" "main" {
name = var.sql_firewall_rule
resource_group_name = local.resourceGroupName
server_name = azurerm_mssql_server.main.name
start_ip_address = "0.0.0.0"
end_ip_address = "0.0.0.0"
}
resource "azurerm_mssql_database" "main" {
name = "${local.raptSqlDatabaseName}-${var.environment}"
server_id = azurerm_mssql_server.main.id
min_capacity = 0.5
max_size_gb = 100
zone_redundant = false
collation = "SQL_Latin1_General_CP1_CI_AS"
sku_name = "GP_S_Gen5_2"
auto_pause_delay_in_minutes = 60
create_mode = "Default"
}
I get an error saying:
Error: waiting for creation of MsSql Database "xxx-xxx-xxx-xxx-Prod" (MsSql Server Name "xxx-xxx-xxx-prod" / Resource Group "rg-xxx-xxx-xxx"): Code="InternalServerError" Message="An unexpected error occured while processing the request.
Before I had to design it all in PS and not bash and use local pool, I never had a problem and this worked fine.
I found this but it's saying the correct error but nothing else seems correct. It is odd because I can build up my other infra fine in the same main.tf file.
https://github.com/hashicorp/terraform-provider-azurerm/issues/13194
I am also noticing that Terraform output is not working:
Here is my output file:
output "sql_server_name" {
value = azurerm_mssql_server.main.fully_qualified_domain_name
}
output "sql_server_user" {
value = azurerm_mssql_server.main.administrator_login
}
output "sql_server_password" {
value = azurerm_mssql_server.main.administrator_login_password
sensitive = true
}
#output "cl_sql_database_name" {
# value = azurerm_mssql_database.cl.name
#}
#output "rapt_sql_database_name" {
# value = azurerm_mssql_database.rapt.name
#}
output "app_insights_instrumentation_key" {
value = azurerm_application_insights.main.instrumentation_key
}
Is there any chance this is linked?

Please use latest terraform version i.e. 1.1.13 and azurerm-provider i.e. 2.92.0 as there were some bugs in previous Azure API version which resulted in 500 Error Code which has been fixed in the recent versions as mentioned in this GitHub Issue . Only after a successful apply , you get the output otherwise it won't get stored if there is an error.
I tested the same code with latest versions on both PowerShell and Bash as below :
provider "azurerm" {
features {}
}
data "azurerm_client_config" "current" {}
locals {
resourceGroupName="ansumantest"
sqlServerName="ansumantestsql"
sql_ad_login="sqladmin"
object_id= data.azurerm_client_config.current.object_id
raptSqlDatabaseName="ansserverdb"
}
variable "location" {
default="eastus"
}
variable "sql_administrator_login" {
default="4dm1n157r470r"
}
variable "sql_administrator_login_password" {
default="4-v3ry-53cr37-p455w0rd"
}
variable "sql_firewall_rule" {
default="ansumantestfirewall"
}
variable "environment" {
default="test"
}
resource "azurerm_mssql_server" "main" {
name = local.sqlServerName
resource_group_name = local.resourceGroupName
location = var.location
version = "12.0"
minimum_tls_version = "1.2"
administrator_login = var.sql_administrator_login
administrator_login_password = var.sql_administrator_login_password
}
resource "azurerm_sql_active_directory_administrator" "main" {
server_name = azurerm_mssql_server.main.name
resource_group_name = local.resourceGroupName
login = local.sql_ad_login
tenant_id = data.azurerm_client_config.current.tenant_id
object_id = local.object_id
}
resource "azurerm_sql_firewall_rule" "main" {
name = var.sql_firewall_rule
resource_group_name = local.resourceGroupName
server_name = azurerm_mssql_server.main.name
start_ip_address = "0.0.0.0"
end_ip_address = "0.0.0.0"
}
resource "azurerm_mssql_database" "main" {
name = "${local.raptSqlDatabaseName}-${var.environment}"
server_id = azurerm_mssql_server.main.id
min_capacity = 0.5
max_size_gb = 100
zone_redundant = false
collation = "SQL_Latin1_General_CP1_CI_AS"
sku_name = "GP_S_Gen5_2"
auto_pause_delay_in_minutes = 60
create_mode = "Default"
}

output "sql_server_name" {

Updated Terraform to latest version didnt really help...
I turned on logging with TF_LOGS (env variable in terraform).
Watching the activity logs in the resource group and i noticed it was building the DB server and then there was an error with AAD and then the DB Server build failed after that. So I removed the AAD work in my main.tf - then i reran the pipeline then it worked fine. Phew...
