For creating Free cluster you shouldn't send any vlans and other parameters ...The machine_type should be "free"

resource "ibm_container_cluster" "cluster" {
  name              = var.cluster_name
  datacenter        = var.worker_zone
  hardware          = var.hardware
  machine_type      = var.plan
}
