what
This PR updates the
data.aws_iam_policy_document.defaultblock in the OpenSearch module to ensure consistent ordering of principals and resources when generating the policy JSON.why
Terraform was detecting in-place updates for
aws_opensearch_domain_policydue to differences in array ordering between what AWS returns and what Terraform generates. This drift is harmless but causes unnecessary terraform plan changes and confusion.This issue is especially apparent after upgrading Terraform or the AWS provider, as newer versions perform a strict literal comparison of JSON arrays.
