terraform и csv для источника данных

Поэтому я пытаюсь использовать Terraform для предоставления нескольких виртуальных машин в vSphere. У меня есть CSV-файл, содержащий информацию для подготовки гостей. Когда я жестко кодирую источники данных, виртуальные машины подготавливаются, но когда я пытаюсь использовать csv для заполнения тех же источников, план Terraform сообщает мне, что центр обработки данных не определен. Я пробовал как CSVDECODE, так и методы интерполяции, ни один из них не работал.

пример csvdecode:

locals {
  virtualmachines = csvdecode(file("${path.module}/virtualmachines.csv"))
}

data "vsphere_datacenter" "dc" {
  count = length(local.virtualmachines)
  name =  local.virtualmachines[count.index].dcname
}

пример интерполяции:

locals {
  virtualmachines = csvdecode(file("${path.module}/server_list.csv"))
}

    # Creating terraform resources from a CSV file using interpolation

    data "null_data_source" "csv_file" {
      inputs = {
        file_data = "${chomp(file("${path.module}/virtualmachines.csv"))}"
               }
    }

  count = "${length(slice(split("\n", lookup(data.null_data_source.csv_file.outputs, "file_data")), 1, length(split("\n", lookup(data.null_data_source.csv_file.outputs, "file_data")))))}"

  triggers = {
    01 = "${element(split(",", element(slice(split("\n", lookup(data.null_data_source.csv_file.outputs, "file_data")), 1, length(split("\n", lookup(data.null_data_source.csv_file.outputs, "file_data")))), count.index)), 0)}"

Сообщение об ошибке от метода интерполяции (никогда не сводится к ресурсу)

A managed resource "output" "server_output" has not been declared in the root module

Любая помощь будет оценена ..
