Terraform Version

1.9.8

AzureRM Provider Version

4.6

Affected Resource(s)/Data Source(s)

Terraform Configuration Files

terraform {
  cloud {
    organization = "my org"
    
    workspaces { 
      name = "Azure"
    }
  }

  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=4.6.0"
    }

    required_version = ">= 1.9.2"
}

provider "azurerm" {
  features {}
  resource_provider_registrations = "none"
  subscription_id = "<redacted>"
}

This problem seems to affect every single type of resource I have (see panic output), so I'm not sure what other config to include here. My config works in 4.1 and without any changes, I get the panic when I try to upgrade to 4.2-4.6.

terraform -v:
Terraform v1.9.8
on darwin_arm64

Error: The terraform-provider-azurerm_v4.6.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.


Plus I get a billion of these messages, for every type of resource I have in my project:

Error: Request cancelled
with azurerm_resource_group.myrg
on resourcegroups.tf line 150, in resource "azurerm_resource_group" "myrg":
resource "azurerm_resource_group" "myrg" {
The plugin.(*GRPCProvider).UpgradeResourceState request was cancelled.

Expected Behaviour

This was working fine on v4.1.0. I changed version to anything from 4.2 to 4.6 and always get the error. I tried various suggestions found online:

• deleting .terraform.lock.hcl file and doing a fresh init
• export GODEBUG=asyncpreemptoff=1
• terraform plan -refresh=false works, but the subsequent terraform plan fails

I'm using HCP terraform as well, so I don't think this is a local computer issue.

Actual Behaviour

Get a crash no matter what I do.

Steps to Reproduce

terraform plan
