Debug Output/Panic Output

│ Error: unknown time zone Europe/Rome
│
│   with module.automation.azurerm_automation_schedule.restart_app_service_during_the_night_schedule[0],
│   on ..\modules\automation\restartAppServiceDuringTheNight.tf line 25, in resource "azurerm_automation_schedule" "restart_app_service_during_the_night_schedule":
│   25: resource "azurerm_automation_schedule" "restart_app_service_during_the_night_schedule" {

Expected Behaviour

The resource "azurerm_automation_schedule" should be created.

Actual Behaviour

I receive the error specified before. I tried also to remove the "timezone" property, since there is a default value (UTC). I receive the same error with reference to UTC timezone.

Steps to Reproduce

1. Create a resource group named "MyResourceGroup"
2. Create a Storage Account named "terraform12345"
3. Create a blob container named "tstate"
4. Create a configuration file like the one specified above.
5. terraform init
6. terraform apply

I see this issue too.

I've been able to confirm that it works as expected in 3.44.1 and it only breaks in 3.45

I have to imagine it's due to #20568 - something different about how the new azure-go-sdk parses time zones?

[mishya02]

Hitting the same issue with v3.45.0.

Updating provider constraint to skip 3.45.0 worked like a charm!
azurerm = { source = "hashicorp/azurerm" version = ">= 3.0.0, != 3.45.0" }

Also, when leaving timezone out of the resource, it defaults to Etc/UTC and also errors saying that timezone is unknown:

CONFIG

resource "azurerm_automation_schedule" "example" {
  name                    = "automation-schedule"
  resource_group_name     = data.azurerm_resource_group.example.name
  automation_account_name = azurerm_automation_account.example.name
  frequency               = "Week"
  interval                = 1
  start_time              = "2024-02-24T17:22:48Z"
}

PLAN

  # azurerm_automation_schedule.example will be created
  + resource "azurerm_automation_schedule" "example" {
      + automation_account_name = "test-aa"
      + expiry_time             = (known after apply)
      + frequency               = "Week"
      + id                      = (known after apply)
      + interval                = 1
      + name                    = "automation-schedule"
      + resource_group_name     = "test-rg"
      + start_time              = "2024-02-24T17:22:48Z"
      + timezone                = "Etc/UTC"
    }

RESULT

│ Error: unknown time zone Etc/UTC
