我正在尝试实现某种机制，让某人可以填写一个变量，该变量定义是要部署 Amazon Linux 机器还是自行创建的打包机。但由于某种原因，它在找到我自己的 AMI 的同时却没有找到 AWS AMI。这是代码：

模块的Main.tf：

    data "aws_ami" "latest" {
  most_recent = true
  owners      = [var.owner]

  filter {
    name   = "name"
    values = [lookup(var.default_ami, var.ami)]
  }
}

resource "aws_instance" "test-ec2deployment" {
  ami                         = data.aws_ami.latest.id

变量.tf：

variable "default_ami" {
  type        = map
  description = "Choose windows 2016 or 2019"
  default = {
    "2016"  = "WIN2016-CUSTOM*"
    "2019"  = "WIN2019-CUSTOM*"
    "linux" = "ami-0fb02dcdd38048fb9"
  }
}

#Above are the options, here you need to make a decision.
variable "ami" {
