无法创建AW​​S：创建Elasticache缓存集群时出错

Question

因此，我正在尝试构建AWS弹性疼痛，但这给了我 错误：

Error: error creating Elasticache Cache Cluster: InvalidParameter: 1 validation error(s) found.
- missing required field, CreateCacheClusterInput.CacheClusterId.

我只是复制terraform文档中的代码。这是代码：

resource "aws_elasticache_cluster" "redis-production" {
  cluster_id            = "${var.cluster-id}"
  engine                = "${local.engine}"
  node_type             = "${local.t2_micro}"
  num_cache_nodes       = 1
  parameter_group_name  = "${var.param-group}"
  engine_version        = "${local.engine_version}"
  port                  = "${local.redis_port}"
}

我使用Terraform v0.12.0 + provider.aws v2.19.0
