Resource 'aws_elasticache_cluster.redis' does not have attribute 'cache_nodes' for variable 'aws_elasticache_cluster.redis.*.cache_nodes'

Pretty sure this syntax is correct, I've used it to export elasticache addresses from a module, but it doesn't like it here?

The error occurs on running a plan

Relevant config:

resource "aws_elasticache_cluster" "redis" {
    count = "${length(split(",",var.elasticache_redis_nodes))}"
}

resource "aws_route53_record" "cache" {
  count = "${length(split(",",var.elasticache_redis_nodes))}"

  records = ["${element(aws_elasticache_cluster.redis.*.cache_nodes.0.address, count.index)}"]
}

The workaround I found is something like the following:

resource "aws_route53_record" "cache" {
  count = "${length(compact(split(",", var.environments)))}"

  zone_id = "${aws_route53_zone.private.zone_id}"
  name    = "${element(split(",", var.environments), count.index)}-cache"
  type    = "CNAME"
  ttl     = "5"
  records = ["${aws_elasticache_cluster.default.*.cache_nodes.0.address[count.index]}"]
}

Update:

Scratch that, I was playing a lot with this and once you plan - and try to apply like this:

resource "aws_route53_record" "cache" {
  count = "${length(compact(split(",", var.environments)))}"

  zone_id = "${aws_route53_zone.private.zone_id}"
  name    = "${element(split(",", var.environments), count.index)}-cache"
  type    = "CNAME"
  ttl     = "5"
  records = ["${aws_elasticache_cluster.default.*.cache_nodes}"]
}

it will fail, although if you then plan and apply the snippet above, it creates the record. 👽

What is the correct workaround for this in 2018?
