Can't set Databricks account admin using Terraform

I want to set the account admin for a service principal in order to create the Unity Catalog metastore. The Terraform code looks like this:

data "databricks_service_principal" "application" {
  count = var.environment == "dev" ? 1 : 0

  application_id = "00000000-0000-0000-0000-000000000000"
}

resource "databricks_service_principal_role" "account_admin" {
  count = var.environment == "dev" ? 1 : 0

  service_principal_id = data.databricks_service_principal.application[0].id
  role                 = "account_admin"
}

This should theoretically work according to the answers in this thread.

But unfortunately I get following error from Terraform for the resource "databricks_service_principal_role": Error: cannot read service principal role: Service Principal has no role

For me this error message is not very useful and I don't know what is wrong here. Is this maybe a bug in the Databricks Terraform provider?

Site notes (if relevant):

• I'm using the newest Databricks Terraform provider (V 1.21)
• The Databricks workspace is deployed in Azure.
• Using the "databrick_user_role" resource and trying to assign the account_admin role to a Databricks user will produce the same error message: User has no role

Looking at the source code on GitHub (Databricks Terraform provider) I found the error message from above but I don't understand why the ReadContext section in there is even executed.

It would be really nice if someone can help me, as I have to enable the Unity Catalog metastore very soon 🙂

The code works just fine, like this:

data "databricks_service_principal" "application" {
  application_id = "xxxxxxxxxx"
}

resource "databricks_service_principal_role" "account_admin" {
  service_principal_id = data.databricks_service_principal.application.id
  role                 = "account_admin"
}

Most probably you have the provider miscofigured - this should happen if you're trying to do this on the workspace level, while it should be done on the account level.

provider "databricks" {
  host = "https://accounts.azuredatabricks.net"
  account_id = "xxxxx"
}

P.S. It could be confusing because right now Unity Catalog resources are created via workspace-level API.
