Are you supplying the architecture_definition_name variable? That is only supported for FSI and SLZ starter modules.

[jaredfholgate]

This is the example input file for the starter module you are using. https://raw.githubusercontent.com/Azure/alz-terraform-accelerator/refs/heads/main/templates/platform_landing_zone/examples/bootstrap/inputs-azure-devops.yaml

You can find the preview docs for the platform_landing_zone starter module here: https://azure.github.io/Azure-Landing-Zones/accelerator/

Same error on my side. Currently I am trying to deploy a Sovereign Landing Zone using the accelerator.

I am using this template:
https://raw.githubusercontent.com/Azure/alz-terraform-accelerator/refs/heads/main/templates/microsoft_cloud_for_industry/sovereign_landing_zone/examples/bootstrap/inputs-local.yaml

Official documentation:
https://learn.microsoft.com/en-us/industry/sovereignty/slz-deployment-config-tasks?tabs=terraform

Header:

# Basic Inputs
iac: "terraform"
bootstrap: "alz_local"
starter: "sovereign_landing_zone"

I updated the input file with all my values and constantly receiving the following error (using the same tools and versions as the author of this issue):

Plan: 45 to add, 0 to change, 0 to destroy.

    }

I get this error only for the top_level_management_group_name. default_prefix and default_postfix seem to work in my case.

I'll see if I can replicate the issue. A change was made by the SLZ team just before Xmas, so could be related to that.

[jaredfholgate]

I think I see the issue for @lrottach. The top_level_management_group_name is missing from the example config files.

With regards to the original issue reported by @lukemurraynz, I have been unable to reproduce that. I have however added some extra checks that may help, but if you supplied the architecture_definition_name variable, it will likely still fail for that.
