这是我的问题：

我的打包器构建文件（为了简单起见，删除了 qemu 构建）

packer {
  required_plugins {
    virtualbox = {
      version = ">=1.0.4"
      source = "github.com/hashicorp/virtualbox"
    }
  }
}


variable "ssh_private_key_file" {
  type    = string
  default = "~/.ssh/id_bas"
}

variable "ssh_timeout" {
  type    = string
  default = "20m"

  validation {
      condition = can(regex("[0-9]+[smh]", var.ssh_timeout))
      error_message = "The ssh_timeout value must be a number followed by the letter s(econds), m(inutes), or h(ours)."
    }
}

我究竟做错了什么？
