### Terraform Version ```shell Terraform v1.15.2 on darwin_arm64 + provider registry.terraform.io/hashicorp/aws v6.42.0 ``` ### Terraform Configuration Files ```terraform locals { # delegations is used to define NS records that delegate subdomains to other # name servers in other AWS accounts. The structure is: # { # "" = { # "" = { # "" = [] # } # } # The "category" is purely for organization and does not affect the Terraform # resource name. delegations = {} # Redacted } resource "aws_route53_record" "delegation" { for_each = { for v in flatten([ for apex, buckets in local.delegations : [ for bucket, entries in buckets : [ for sub, ns in entries : [ { name = "${sub}.${apex}", apex = apex, ns = ns }, # We automatically create a "cname-" delegation, since it is commonly # used by the external-dns controller for TXT heritage records. { name = "cname-${sub}.${apex}", apex = apex, ns = ns }, ] ] ] ]) : v.name => v } zone_id = aws_route53_zone.this[each.value.apex].id name = each.key type = "NS" ttl = 172800 records = each.value.ns } ``` ### Debug Output Sorry I can't get the debug output anymore, since I worked around it already with targeted-applies. ``` Plan: 156 to add, 0 to change, 0 to destroy.

The `for_each` depends entirely on static locals. Nothing is derived from resources or data sources. I expect the apply to work. ### Actual Behavior Once the apply starts, Terraform immediately crashes with a nil pointer dereference panic. ### Steps to Reproduce 1. `terraform apply` 2. Type `yes` ### Additional Context I am able to workaround this by applying using `-target`. I got through my 156 instances by working in batches of 10. ### References Possibly related to https://github.com/hashicorp/terraform/issues/38550, but I was directed to open a new issue. ### Generative AI / LLM assisted development? _No response_
