[lovrek93]

Terraform Core Version

1.0.9

AWS Provider Version

4.51.0

Affected Resource(s)

aws_route53_record

Expected Behavior

Alias configuration in TF should create Alias configuration.

Actual Behavior

Getting following error:

Error: Too many alias blocks

  on 25-records.tf line 26, in resource "aws_route53_record" "records":
  26:     content {

No more than 1 "alias" blocks are allowed

Relevant Error/Panic Output Snippet

Error: Too many alias blocks

  on 25-records.tf line 26, in resource "aws_route53_record" "records":
  26:     content {

No more than 1 "alias" blocks are allowed

Terraform Configuration Files

"records":{
"test": {
      "name": "test.cdn",
      "type": "A",
      "alias": {
        "fqdn": "example.net.",
        "zone_id": "zoneID",
        "evaluate_target_health": false
      }
    }
}

  # Alias configuration
  dynamic "alias" {
    iterator = al
    for_each = lookup(var.records[each.key], "alias", {})
    content {
      name                   = lookup(var.records[each.key].alias, "fqdn", null)
      zone_id                = lookup(var.records[each.key].alias, "zone_id", null)
      evaluate_target_health = lookup(var.records[each.key].alias, "evaluate_target_health", null)
    }
  }

Steps to Reproduce

Adding a new record with alias configuration and using newest AWS provider gives the error.

Debug Output

Panic Output

No response

Important Factoids

This happens only on version 4.51.0 (works on all prior versions).
I found this issue that mentions the breaking change in file internal/service/route53/record.go on line 91
It seems to me that this breaking change was already implemented in version 4.51.0 and hence this problem is happening.
My advice would be revert "alias" for record to previous configuration (like on 4.50.0 for example).

Hi @lovrek93, thank you for submitting this. The provider was previously failing silently when more than one alias block was submitted.

It looks like you're trying to conditionally create the alias block if the record in the variable contains an alias. Based on the error message returned by Terraform, it looks like the for_each statement is returning more than one record.

I've tried debugging this, but I'm not able to simply place the dynamic block in an aws_route53_record resource because it does not parse. Could you please update this issue with the full aws_route53_record resource?
