Broken package installation using Ansible on debian 11 Bullseye

I woud like to install debian packages using Ansible 2.7.7 on Debian testing (yet)

I try to execute this simple task:

  tasks:
  - name: install basic packages
    apt:
      name: ['mc', 'htop', 'strace','sudo','screen','lshw', 'postfix', 'etckeeper']
      state: present

But the installation is failing with strange message:

TASK [install basic packages] *********************************************************************************
fatal: [webserver.vitexsoftware.cz]: FAILED! => {"changed": false, "msg": "Could not import python modules: apt, apt_pkg. Please install python-apt package."}
        to retry, use: --limit @/home/vitex/Projects/VitexSoftware/Ansible/playbooks/orchestrate.retry

The requied python package for apt is installed as python3-apt

vitex@webserver:~/Projects/VitexSoftware/DockerTools$ aptitude search python | grep '-apt'
i A python-apt-common - Python interface to libapt-pkg (locales)
p  python-apt-dev - Python interface to libapt-pkg (development files)
p  python-apt-doc - Python interface to libapt-pkg (API documentation)
i  python3-apt - Python 3 interface to libapt-pkg
p  python3-apt-dbg - Python 3 interface to libapt-pkg (debug extension)
v  python3-apt-dbg:any - 
v  python3-apt:any - 
p  python3-aptly - Aptly REST API client and useful tooling - Python 3.x
v  python3.9-apt - 
v  python3.9-apt-dbg - 
v  python3.9-apt-dbg:any - 
v  python3.9-apt:any - 

There is an closed unresolved issue on github: https://github.com/ansible/ansible/issues/73535 which wont help me somehow.

How to make working as on Debian 10 ?
