It is, the change is detected on the second `terraform apply` and not the first one. Since `null_resource.test` resource detects the change in first `terraform plan`, it must be some issue with azurerm provider and not terraform core. ### Steps to Reproduce _No response_ ### Important Factoids _No response_ ### References _No response_
