Can we cron schedule bash file execution in Terraform

Question

Can we cron schedule local_exec to execute the bash file that having the multiple commands in Terraform? I tried the [google_cloud_scheduler_job][1]

resource "google_cloud_scheduler_job" "job" {
  name = "test-job"
  description = "test job"
  schedule = "*/2 * * * *"
  provisioner "local-exec" {
    command = "${path.module}/bash_file.sh"
  }
}

But I am getting an error

Error: ExactlyOne

  on main.tf line 366, in resource "google_cloud_scheduler_job" "job":
 366: resource "google_cloud_scheduler_job" "job" {

"app_engine_http_target": one of
`app_engine_http_target,http_target,pubsub_target` must be specified

Any suggestions will be appreciated. Thank you.

You can't schedule local-exec at all, and certainly not with a Google cloud scheduler. This is not how local-exec works at all, or what it is intended to do. How would the Google scheduler be able to reach into your computer to locally execute a bash script?

You probably want to build whatever your bash script is doing into a Google Cloud Function, and provision that function via Terraform.
