Terraform: resource/aws_route53_record: Plan shows pending changes when nothing changed

[jimmycuadra]

Terraform Version

Terraform v0.6.16

Affected Resource(s)

• aws_route53_record
  

  Terraform Configuration Files

resource "aws_route53_record" "foo-example-com-A" {
    zone_id = "ZREDACTED"
    name    = "foo.example.com"
    type    = "A"

    alias {
        name    = "dualstack.redacted.us-east-1.elb.amazonaws.com"
        zone_id = "ZREDACTED"
        evaluate_target_health = false
    }
}

Expected Behavior

If the configuration is not changed between Terraform runs, no pending changes should be reported by terraform plan.

Actual Behavior

Running terraform plan results in the following output:

~ aws_route53_record.foo-example-com-A
    alias.3007436033.evaluate_target_health: "" => "false"
    alias.3007436033.name:                   "" => "dualstack.redacted.us-east-1.elb.amazonaws.com"
    alias.3007436033.zone_id:                "" => "ZREDACTED"
    alias.3868099092.evaluate_target_health: "false" => "false"
    alias.3868099092.name:                   "dualstack.redacted.us-east-1.elb.amazonaws.com." => ""
    alias.3868099092.zone_id:                "ZREDACTED" => ""

Steps to Reproduce

1. Apply the initial version of the resource with terraform apply.
2. Run terraform plan.
