Error when trying to use data source ibm_container_cluster for existing lite IKS

[eiri]

Creating a data source ibm_container_cluster for existing lite IKS throws an error.

Terraform Version

$ terraform -v
Terraform v0.14.7
+ provider registry.terraform.io/hashicorp/kubernetes v2.0.2
+ provider registry.terraform.io/ibm-cloud/ibm v1.20.1

Affected Resource(s)

• ibm_container_cluster

Terraform Configuration Files

terraform {
  required_providers {
    ibm = {
      source  = "IBM-Cloud/ibm"
      version = "~> 1.20.0"
    }
  }
}

variable "ibmcloud_api_key" {}

provider "ibm" {
  ibmcloud_api_key = var.ibmcloud_api_key
  region           = "us-south"
}

data "ibm_container_cluster" "sandbox" {
  name = "sandbox"
}

Expected Behavior

Command terraform plan should work correctly.

Actual Behavior

Command terraform plan throws an error "The specified cluster is a free cluster. Ingress is not supported for free clusters."

I believe the reason for this issue is that the error message on missing alb changed, so while provider tried to skip an error message "The specified cluster is a lite cluster." the actual error message now has a word "free" instead of "lite".

Steps to Reproduce

Both terraform plan or terraform refresh reproduce the issue.
