Hostvar syntax cannot receive extra variable as hostname

ph flag
azk

I'm is trying to use an extra vars to set the hostname in the "hostvars" variable to get the uuid from other host. But it seems that don't catches the variable's value.
This is the run line:

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

This is the playbook

---
- 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

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

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

This is the Error result

Did ansible actually gather the facts for `target_host`? You can't use a fact for the target host unless you either gather that fact, or you have fact caching enabled and the cache is still valid. What happens if you just do a `debug` on the var `hostvars[target_host]`?

target_host receives the extra variable "vmname" that get the hostname with the -e option when I run the playbook

If the only host is ``localhost`` then there are no other ``hostvars`` except ``hostvars.localhost`` available to the play. Test it. Print an existing fact. Edit the question and make it [Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example). Remove the redundant variables and code, e.g. 1) Remove ``variables vcenter_*`` 2) Remove options ``-i`` and ``--vault-id``. The options do not influence the problem. You don't provide the files anyway.

The ansible_product_uuid was not gathered. The hostvars variable works fine.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
