Ansible and Opennebula: ProtocolError for https://myopennebulaserver/RPC2: 401 401 Client Error: Unauthorized

Question

I want to use ansible for manage opennebula. In my ansible server, I have installed community.general (ansible-galaxy collection), pyone and oca-decorators. In my opennebula server, I have installed pyone and oca-decorators.

I have created a playbook with this content:

- hosts: myopennebulaserver
  become: false
  become_method: sudo
  tasks:
  - name: Gather facts about all images
    community.general.one_image_info:
     api_url: https://myopennebulaurlserver
     api_username: "myopennebulawebuserserver"
     api_password: "myopennebulawebpasswordserver"
    register: result

When I exec the playbook I obtent this error:

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: xmlrpclib.ProtocolError: <ProtocolError for https://myopennebulaurlserver/RPC2: 401 401 Client Error: Unauthorized>

Any suggestions?

Thank you.
