cluster_config_file does not work with ~ or $HOME

Unfortunately the example from the README does not work for me. I get an error when I try to use cluster_config_file = "~/.kube/db2u-config":

The same happens for cluster_config_file = "$HOME/.kube/db2u-config":

Here is the terraform snippet I'm using:

module "dev_software_olm_release" {
  source = "github.com/cloud-native-toolkit/terraform-k8s-olm"

  cluster_config_file = "~/.kube/db2u-config"
  cluster_version     = "1.20"
  cluster_type        = "kubernetes"
  olm_version         = "v0.20.0"
}

When I switch to cluster_config_file = "/home/<username>/.kube/db2u-config" it runs without any issue.

Fixed by using pathexpand (https://www.terraform.io/language/functions/pathexpand):

module "dev_software_olm_release" {
  source = "github.com/cloud-native-toolkit/terraform-k8s-olm"

  cluster_config_file = pathexpand("~/.kube/db2u-config")
  cluster_version     = "1.20"
  cluster_type        = "kubernetes"
  olm_version         = "v0.20.0"
}
