[Bug]: perpetual diff when ebs_enabled is set to false, cannot zero values because of validation

[joelmarty]

Terraform Core Version

1.9.6

AWS Provider Version

5.65.9

Affected Resource(s)

aws_opensearch_domain

Expected Behavior

Setting ebs_options.ebs_enabled to false ignores the rest of EBS arguments for diff and/or validation.

Actual Behavior

Setting ebs_enabled to false produces a perpetual diff as it sets the other ebs arguments to zero values on apply:

At the same time, trying to set those arguments to the same zero values in the configuration to avoid the diff fails because the validation requires specific values:

Terraform Configuration Files

resource "aws_opensearch_domain" "opensearch" {

  domain_name     = "test"
  ebs_options {
    ebs_enabled = false

    volume_type = "gp3"
    throughput  = 125
    iops        = 3000
  }

}
