Problema de back-end do Terraform Azure

Estamos usando o Azure como back-end para nosso código Terraform. Abaixo está o código.

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 3.40.0"
    }
  }

  backend "azurerm" {
    resource_group_name  = "test"
    storage_account_name = "test"
    container_name       = "test"
    key                  = "test.tfstate"
    tenant_id            =  "abc"
  }
}

provider "azurerm" {
  features {}
  alias               = "new-new"
  subscription_id     = var.another_subscription
}

provider "azurerm" {
  features {}
}

E fiz login como usuário principal do serviço usando o comando abaixo:

az login --service-principal -t tenant-id-here -u object-id-of-sp -p client-secret-of-sp

E quando faço terraform initisso dá o erro abaixo:
