R53 Delegation Set: Member must have length less than or equal to 32

[ghost]

This issue was originally opened by @david-peters-aitch2o as hashicorp/terraform#24250. It was migrated here as a result of the provider split. The original body of the issue is below.

Terraform Version

Terraform v0.12.21
+ provider.aws v2.44.0
...

Terraform Configuration Files

resource "aws_route53_zone" "main" {
  name = "${terraform.workspace}.fubarfubar.com"
 delegation_set_id = "aws_route53_delegation_set.main.id"
  tags = {
    Environment = "${terraform.workspace}.terraform"
  }
}
...

Debug Output

Crash Output

Expected Behavior

If ${terraform.workspace} is dev and domain is fubarfubar.com there should be no issues

Actual Behavior

Terraform fails with Error: error creating Route53 Hosted Zone: InvalidInput: 1 validation error detected: Value 'aws_route53_delegation_set.main.id' at 'resourceId' failed to satisfy constraint: Member must have length less than or equal to 32 status code: 400, request id: 0f396743-1af5-417c-91e3-3d4a1ae23672

Steps to Reproduce

Additional Context

Changing the domain fubarfubar.com to a.com or something shorter works, it seems Terraform is taking ${terraform.workspace} as part of the domain when it calculates the domain name length.

This only happens when delegation_set_id is part of the aws_route53_zone resource

You're using a string literal "aws_route53_delegation_set.main.id" so that's 34 characters.

If you're using Terraform 0.12 then this should just be:

resource "aws_route53_zone" "main" {
  name              = "${terraform.workspace}.fubarfubar.com"
  delegation_set_id = aws_route53_delegation_set.main.id

  tags = {
    Environment = "${terraform.workspace}.terraform"
  }
}

but if you're using Terraform 0.11 or lower then you need to use the interpolation syntax:

resource "aws_route53_zone" "main" {
  name              = "${terraform.workspace}.fubarfubar.com"
  delegation_set_id = "${aws_route53_delegation_set.main.id}"

  tags = {
    Environment = "${terraform.workspace}.terraform"
  }
}

There should probably be a ValidateFunc on this as well to check this is no more than 32 characters at plan/validate time.

Length validation for this argument has been merged and will release with version 3.23.0 of the Terraform AWS Provider, likely tomorrow. Thank you to @FrancisLfg for the implementation. 👍
