alisdair · 2021-06-18T18:26:30Z

Thanks for reporting this. Based on the stack trace and the error, I'm having trouble finding a reproduction case. Here's what I've tried:

locals {
  natgw_keys         = sensitive(toset(["a", "b", "c"]))
  onprem_cidr_blocks = toset([sensitive("z")])
}

output "product" {
  value = nonsensitive(setproduct(local.natgw_keys, local.onprem_cidr_blocks))
}

This validates and plans successfully. Can you adjust this to be more similar to your config in order to reproduce the panic?

tbugfinder · 2021-06-19T20:25:51Z

This is a code to replay.

locals {
  availability_zones_short = toset([substr(data.aws_availability_zones.available.names[0], -2, -1), substr(data.aws_availability_zones.available.names[1], -2, -1)])
  natgw_keys               = toset([for k in local.availability_zones_short : "natgw-${k}"])
  onprem_cidr_blocks = toset(["10.0.0.0/8", "172.16.0.0/12", "192.168.0.0/16" ])
}

data "aws_availability_zones" "available" {
  state = "available"
}

output "setproduct" {
  value = setproduct(local.natgw_keys, local.onprem_cidr_blocks)
}

alisdair · 2021-06-21T15:03:49Z

Thanks! This crashes for me with terraform validate.

alisdair · 2021-06-21T15:56:47Z

Thanks again for the report. I have a fix for this in the upstream cty library here: zclconf/go-cty#109

alisdair · 2021-06-21T16:54:26Z

Will be fixed in the upcoming 1.0.1 release.
