Steps to reproduce the issue:
My module uses the following:

provider "k8s" {
  load_config_file = "false"
  config_path      = "${path.module}/tmp/.kube/config"
}

data "local_file" "istio_manifest" {
  filename = "${path.module}/tmp/istio-manifest.yaml"
}

# kubectl apply -f generated-manifest.yaml --kubeconfig=.kube/config
resource "k8s_manifest" "istio_install" {
  content = data.local_file.istio_manifest.content
}

istio-manifest.yaml

The main issue is here that we are not supporting multi-resource YAML files as have been described previously in #7 You will have to use the workaround in the issue.

I will fix the provider to detect this case rather than panicking.
