Local-exec using powershell not executing commands - terraform

Question

Having some issues when trying to run Powershell commands through a null-resource 'local-exec". I’m trying to run a PowerShell command with some additional parameters:
provisioner “local-exec” {
interpreter = [“PowerShell”, “-Command”]
command = <<EOT
$ResourceGroupName = '"${module.rg.resource_group.name}"'
$FunctionAppName = '"${var.function_apps[each.key].name}"'
$SubscriptionId = '"${var.subscriptions.id}"'
# Option 1 - does nothing
Get-AzFunctionApp -ResourceGroupName $ResourceGroupName -Name $FunctionAppName -SubscriptionId $SubscriptionId
# Option 2 - does nothing
(Get-AzFunctionApp -ResourceGroupName $ResourceGroupName -Name $FunctionAppName -SubscriptionId $SubscriptionId)
# Option 3 - shows the correct cmd line with correctly expanded variables but does not execute the command
"Get-AzFunctionApp -ResourceGroupName $ResourceGroupName -Name $FunctionAppName -SubscriptionId $SubscriptionId"
# Option 4 - when I hardcode the values it works
Get-AzFunctionApp -ResourceGroupName "real_rg_name" -Name "real_rg_appname" -SubscriptionId real_subscr_id
EOT
}
Only when I hardcode the values the Az command executes.

Answer 1

I tested the same with something like below :
provider "azurerm" {
features{}
}
data "azurerm_resource_group" "example"{
name = "ansumantest"
}
variable "function_apps" {
default = ["ansumantestfunc1","ansumantestfunc2"]
}
variable "Subscription" {
default = "948d4068-xxxx-xxxx-xxxx-xxxxxxxxxxx"
}
resource "null_resource" "example2" {
count = length(var.function_apps)
provisioner "local-exec" {
command = <<Settings
$ResourceGroupName = "${data.azurerm_resource_group.example.name}"
$FunctionAppName = "${var.function_apps[count.index]}"
$SubscriptionId = "${var.Subscription}"
Get-AzFunctionApp -ResourceGroupName $ResourceGroupName -Name $FunctionAppName -SubscriptionId $SubscriptionId
Settings
interpreter = ["PowerShell", "-Command"]
}
}
Output:
