Experiment "module_variable_optional_attrs" is no longer available

Getting an error when trying to use cce module with latest terraform version:

[linux]$ cat cce.tf
module "cce" {
  source             = "registry.terraform.io/iits-consulting/project-factory/opentelekomcloud//modules/cce"
  name               = "var.${cce_cluster_name}_test"
  autoscaling_config = {
    nodes_max = 8
  }
  cluster_config     = {
    vpc_id            = module.vpc.vpc_id
    subnet_id         = lookup(module.vpc.subnet_list, "tos-cce")
    cluster_version   = "v1.21"
    high_availability = true
    enable_scaling    = true #set this flag to false to disable auto scaling
  }
  node_config        = {
    availability_zones = ["eu-ch2a", "eu-ch2b"]
    node_count         = 3
    node_flavor        = local.node_spec_default
    node_storage_type  = "SSD"
    node_storage_size  = 100
  }
}

Error is:

Hi thanks for pointing that out. But the latest stable version is still 1.2.7 https://www.terraform.io/downloads

You are currently using a alpha version which i would not recommend to use till it becomes stable.

We will try it out with 1.3.0 when it becomes stable and will remove the experiments part from the versions.tf

It is also important to note that the syntax for optional attributes change entirely with 1.3.x, with which we will have to make a major release following the new syntax.

@generalpax is fixxed now in version 5.0.0
