Error: Insufficient features blocks! Finally

Terraform Providers Azure
1

I know there are many (actually 5) topics with the same problem statement but there is no clear understanding and solution.

I’d like to make it resolved here.

The error:

Error: Insufficient features blocks

  on <empty> line 0:
  (source code not available)

At least 1 "features" blocks are required.

Version:

Terraform v1.1.5
on linux_amd64
+ provider registry.terraform.io/hashicorp/azurerm v2.95.0
+ provider registry.terraform.io/hashicorp/external v2.2.0
+ provider registry.terraform.io/hashicorp/null v3.1.0
+ provider registry.terraform.io/hashicorp/vault v3.3.1

The codebase has a dedicated file with the name gen_provider.tf

# Generated by Terragrunt. Sig: nIlQXj57tbuaRZEa
provider "azurerm" {
  subscription_id = XXX
  client_id       = XXX
  client_secret   = XXX
  tenant_id       = XXX
  features {}
}

terraform {

terraform validation passed successfully. (it checks azurerm feature block gap)

I’m happy to provide any additional information (code, logs, etc).

The situation is really weird.

here is the minimal tf to reproduce the issue

terraform {
  backend "azurerm" {
    storage_account_name = "XXX"
    container_name       = "XXX"
    key                  = "XXX"
    access_key           = "XXX"
  }
}

provider "azurerm" {
  features {}
}

/* 
data "azurerm_storage_account" "level0" {
  name                = "XXX"
  resource_group_name = "XXX"
} */
  • plan worked w/o data “azurerm_storage_account” “level0”
  • with data “azurerm_storage_account” “level0” it false with no features {} block issue.
Error: Insufficient features blocks

At least 1 "features" blocks are required

I have the same issue (error code) with bit different conditions:

2 providers - “microsoft/azuredevops” and “hashicorp/azurerm”
normally (previously worked with azuredevops) the first provider doesn’t accept any features in provider block:

Error: Unsupported block type
│
│   on modules\ADO\provider.tf line 13, in provider "devops":
│   13:   features {}
│
│ Blocks of type "features" are not expected here.

when I’m removing features block - then I get:

╷
│ Error: Insufficient features blocks
│
│   on <empty> line 0:
│   (source code not available)
│
│ At least 1 "features" blocks are required.

WTF???

my providers looks like:

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = ">= 3.2.0"
    }
  }
}

provider "azurerm" {
  features {
    log_analytics_workspace {
      permanently_delete_on_destroy = true
    }
    resource_group {
      prevent_deletion_if_contains_resources = true
    }
    key_vault {
      purge_soft_delete_on_destroy               = true
      purge_soft_deleted_secrets_on_destroy      = true
      purge_soft_deleted_certificates_on_destroy = true
    }
  }
  skip_provider_registration = true
}

and

terraform {
  required_providers {
    devops = {
      source  = "microsoft/azuredevops"
      version = ">= 0.2.1"
    }
  }
}

provider "devops" {
  org_service_url       = var.ado_organization_url
  personal_access_token = var.ado_pat
}

and versions are:

Terraform v1.1.9
on windows_386
+ provider registry.terraform.io/hashicorp/azurerm v3.3.0
+ provider registry.terraform.io/hashicorp/random v3.1.3
+ provider registry.terraform.io/microsoft/azuredevops v0.2.1

(searching rest of a code for words provider/providers/etc… is not giving me any other matches - read that as there is no other places with provider definitions.)

even disabling (commenting) whole 2nd provider (azuredevops) and removing module/ADO from code tree - I’m getting the same error type.
Funny part:
before I started modifying code for azuredevops and it’s functions - the code was running correctly, now removing everything back is not - magic…
