The provider has deprecated the "iam_service_id" attribute in favor of "iam_id" for the ibm_iam_service_policy resource:

Warning: Argument is deprecated

 2025/08/26 17:13:14 Terraform refresh | release. Please use iam_id field instead.

Looks like you are using ibm_iam_service_policy here -> https://github.com/terraform-ibm-modules/terraform-ibm-devsecops-alm/blob/main/prereqs/main.tf
