Steps to Reproduce

1. create main.tf in empty directory
2. create scripts directory
3. create file named auth_handler.py inside of the scripts directory, content unnecessary
4. terraform validate

Additional Context

Validates properly on terraform 1.9.8-1 or:

Terraform v1.9.8
on linux_amd64
+ provider registry.terraform.io/hashicorp/archive v2.6.0

Your version of Terraform is out of date! The latest version
is 1.10.0. You can update by downloading from https://www.terraform.io/downloads.html
