Running Powershell script in Terraform module - linux

Question

Am currently running some Terraform to create resources in Azure. We have a module we have written to create a resource group with a bunch of variables. The provider currently does not allow the creation of budgets and cost alerts but the Powershell modules do. I thought we could then add a Powershell script to carry out the settings. I seem to be hitting a snag where I cannot quite work out how to address the Powershell script. I have the following:
resource "null_resource" "PowerShellScriptRunAlways" {
triggers = {
always_run = "${timestamp()}"
}
provisioner "local-exec" {
command = ".'${path.module}//pwsh//costalert.ps1 -subscriptionID \"${var.azure_subscription_id}\" -tenantID \"${var.azure_tenant_id}\" -clientID \"${var.azure_client_id}\" -clientSecret \"${var.azure_client_secret}\" -budgetAmount \"${var.budgetAmount}\" -rgName \"${azurerm_resource_group.this.name}\" -emailAddresses \"${var.emailAddresses}\"'"
interpreter = ["pwsh", "-Command"]
}
}
using pwsh as this is running on a Linux Jenkins agent. This is part of a module where the ps1 file is under "root module directory/pwsh" but it seems to yield the following:
Error: Error running command '.'.terraform/modules/rg_test\pwsh\costalert.ps1 -subscriptionID "xxxxx" -tenantID "xxxxxxx" -clientID "xxxxxx" -clientSecret "xxxxx" -budgetAmount "1000" -rgName "rg-da_test-sbxeng-001" -emailAddresses "xxxxxx"'': exit status 1. Output: . : The module '.terraform/modules/rg_test' could not be loaded. For more information, run 'Import-Module .terraform/modules/rg_test
+ .'.terraform/modules/rg_test\pwsh\costalert.ps1 -subscriptionID
It seems to be switching the path but cannot seem to make it pick up the script and run it. Does anyone have any suggestions?

Isn't this a quoting issue?
I can successfully execute this pwsh null resource from a terraform module in an Azure DevOps linux agent. Note that only the script path is single quoted, while in your example you've got the whole command single quoted.
resource "null_resource" "create_sql_user" {
provisioner "local-exec" {
command = ".'${path.module}\\scripts\\create-sql-user.ps1' -password \"${random_password.sql_password.result}\" -username \"${var.sql_username}\" -sqlSaConnectionString \"${var.sql_server_connectionstring}\" -databaseName \"${azurerm_sql_database.db.name}\" "
interpreter = ["pwsh", "-Command"]
}
depends_on = [azurerm_sql_database.db]
}
