aws_route53_resolver_rule domain_name value "." is now broken

[mingfang]

aws_route53_resolver_rule domain_name with value "." is legal and essential.
It was working until this commit.

ee459d6#diff-c728f6192d56e060a6fa9964d8d90832

that removed suppressRoute53ZoneNameWithTrailingDot() from aws/diff_suppress_funcs.go
This is a critical problem for me with no workarounds besides manually creating the rule.

I found that downgrading the AWS plugin can workaround this problem.

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "2.69.0"
    }
  }
}

Being able to create a rule for the . domain name is explicitly called out in the AWS documentation:

If you want to forward all queries to your network, you create a rule, specify "." (dot) for the domain name, and associate the rule with the VPCs for which you want to forward all DNS queries to your network.

Attempting to create a rule with domain_name = "." results in the error:

        Error: error creating Route 53 Resolver rule: InvalidParameter: 1 validation error(s) found.
        - minimum field size of 1, CreateResolverRuleInput.DomainName.

The fix for this has been merged and will release with version 3.5.0 of the Terraform AWS Provider, very shortly. Thanks to @ewbankkit for the implementation. 👍
