In TF 0.13+ all list elements must have the same type

[apeabody]

TL;DR

Historically list(any) was used for

terraform-google-gcloud/variables.tf

Line 35 in 6789fa7

variable "module_depends_on" {

However subsequent to hashicorp/terraform#26265, all list elements must have the same type. So for example this fails: module_depends_on = [time_sleep.wait_300_seconds, null_resource.test] The given value is not suitable as all list elements must have the same type.

@bharathkkb - When you have time, could you confirm/feedback as if so this might apply to several modules? The vast majority of module_depends_on only have a single argument, are therefore work as expected. However we might want to switch to a string or update the documentation to clarify the situation.

@apeabody updating docs to clarify this sgtm. IIUC end users can also workaround this by type coercion if needed.

A workaround could be to use an intermediate null_resource depending on the real resources:

resource "null_resource" "depends_on_sleep_and_test" {
  triggers   = { always_run = timestamp() }
  depends_on = [time_sleep.wait_300_seconds, null_resource.test]
}

module "execute_create_admin" {
  source            = "terraform-google-modules/gcloud/google"
  module_depends_on = [null_resource.depends_on_sleep_and_test]
}
