Terraform 无法正确引用映射内列表中的值

我试图引用地图列表中的一个值，但似乎无法让terraform识别它是一个字符串

下面是我正在处理的模块以及定义的变量

resource "aws_transfer_user" "aws_transfer_users" {

  for_each = var.transfer_users_and_keys

  server_id = aws_transfer_server.aws_transfer_service.id
  user_name = each.key
  role = aws_iam_role.aws_transfer_role.arn

  home_directory = format("/%s/%s",var.transfer_users_and_keys[each.value[1]],var.transfer_users_and_keys[each.key])

  tags = {
    Name = each.key
    Project = var.product_name
    Terraform = true
  }
}

出于某种原因，当我从列表中调用该值时，它会给出以下错误：

on main.tf line 38, in resource "aws_transfer_user" "aws_transfer_users":
  38:   home_directory = format("/%s/%s",var.transfer_users_and_keys[each.value[1]],var.tran
sfer_users_and_keys[each.key])
    |----------------
    | each.value[1] is "bucket-dev-client"
    | var.transfer_users_and_keys is map of list of string with 2 elements 

The given key does not identify an element in this collection value.

下面是我正在创建的变量：

transfer_users_and_keys = {
    format("key-%s",local.environment) = ["value.pub",tostring(local.sftp_bucket[0])]
    format("key-%s02",local.environment) = ["value02.pub",local.sftp_bucket]
}
sftp_bucket = [format("bucket-%s-client",local.environment)]

---

这里的目标是基于“transfer_users_and_keys”变量（tostring（local.sftp_bucket[0]）中的第二个值构建主目录。

当为每个使用

时，您不需要一直引用该变量并为其编制索引。更改：

home_directory = format("/%s/%s",var.transfer_users_and_keys[each.value[1]],var.transfer_users_and_keys[each.key])

简单地

home_directory = format("/%s/%s", each.value[1], each.key)

感谢您在问题中提供足够的信息，以便我能够回答！
home_directory = format("/%s/%s", each.value[1], each.key)
