How to retrieve the null_resource returned value?

I also use the external data source for a similar use case.

data "external" "policy_document" {
  program = ["bash", "${path.module}/get-policy-doc.bash"]

  query = {
    lb_cntrl_version = var.lb_cntrl_version
  }
}

resource "aws_iam_policy" "this" {
  name        = local.identifier
  policy = base64decode(data.external.policy_document.result.ecoded_doc)
}

And here is the script.

#!/usr/bin/env bash

set -euo pipefail

eval "$(jq -r '@sh "lb_cntrl_version=\(.lb_cntrl_version)"')"

policy_document=$(curl -sS https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v${lb_cntrl_version}/docs/install/iam_policy.json)

ecoded_doc=$(echo $policy_document | base64 -w 0)

jq -n --arg ecoded_doc "$ecoded_doc" '{"ecoded_doc":$ecoded_doc}'
