What is the bug?

terrafrom: OpenSearch index throws error below.

[BUG] Error: HEAD HealthCheck failed: This is usually due to network or permission issues. The underlying error isn't accessible, please debug by disabling health checks.

Files:
provider.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "> 5.48"
}
opensearch = {
source = "opensearch-project/opensearch"
version = "> 2.3.1"
}
}
}

How can one reproduce the bug?

Plan + apply an index using v2.3.1 of the opensearch provider

What is the expected behavior?

Should be able to create index in AWS OpenSearch.

What is your host/environment?
