Auth module crash with 4.49 google provider

[cliles]

TL;DR

When use_private_endpoint is set to true, auth module will fail to plan.

Expected behavior

use_private_endpoint to work.

Observed behavior

On a terraform plan:

module.target_repo.module.kubernetes-engine_auth.data.google_client_config.provider: Refreshing state...
module.target_repo.module.kubernetes-engine_auth.data.google_container_cluster.gke_cluster: Refreshing state...

Error: Invalid address to set: []string{"addons_config", "0", "config_connector_config"}

  on .terraform/modules/target_repo.kubernetes-engine_auth/modules/auth/main.tf line 26, in data "google_container_cluster" "gke_cluster":
  26: data "google_container_cluster" "gke_cluster" {

Terraform Configuration

module "kubernetes-engine_auth" {
  source  = "terraform-google-modules/kubernetes-engine/google//modules/auth"
  version = "24.1.0"

  cluster_name         = var.cluster_name
  location             = var.regionality
  project_id           = local.project_id
  use_private_endpoint = true
}

Terraform Version

https://github.com/hashicorp/terraform-provider-google/releases/tag/v4.49.0

Additional information

Looks like the GA provider just released a new datasource.

This seems to be due to this change since config connector is now GA: hashicorp/terraform-provider-google#13380

Same issue here!

Facing same issue, I have to lock the google provider to not use 4.49:

terraform {
  required_version = ">= 1.3"

  required_providers {
    google = {
      source  = "hashicorp/google"
      version = ">= 4.44, < 4.49.0"
    }
    google-beta = {
      source  = "hashicorp/google-beta"
      version = ">= 4.44, < 4.49.0"
    }
  }
}

This appears to be the upstream issue: hashicorp/terraform-provider-google#13507

Version 4.50 google provider is out last night, and it has the same issue. Would you open this issue, or create another one?
