Hostvar 语法无法接收额外的变量作为主机名

我正在尝试使用额外的变量在“hostvars”变量中设置主机名，以便从其他主机获取 uuid。但似乎无法捕获变量的值。
这是运行行：

$ ansible-playbook -i ../Inventory/my_inventory --vault-id vaultfile getuuid.yml -e vmname=testhost

这是剧本

---
- hosts: localhost
  gather_facts: true

  vars:
    vcenter_hostname: 'vcenter.bio.local'
    vcenter_username: 'bio.local\ansible'
    vcenter_password: !vault |
          $ANSIBLE_VAULT;1.1;AES256
          33376437643462306363663235353732613838623561616532383236633563663938656236643861

          37383766643536313639313337363263653537613238396136393581373932633166343834383162

          6434
    target_host: "{{ vmname }}" 
    vm_uuid: "{{ hostvars[target_host]['ansible_product_uuid'] }}"

  tasks:
    - name: Print host
      debug:
        msg: "{{ vm_uuid }}"

这是错误结果

未收集 ansible_product_uuid。hostvars 变量工作正常。
