| value = "${element(coalescelist(compact(list(module.dns.hostname)), aws_elasticache_replication_group.default.*.primary_endpoint_address), 0)}" | |
| value = "${coalesce(module.dns.hostname, join("", aws_elasticache_replication_group.default.*.primary_endpoint_address)}" |
If enabled=false, module.dns.hostname will be empty and aws_elasticache_replication_group.default.*.primary_endpoint_address will be empty list.
does element work on an empty list?
