How to Use Ansible_local with Molecule

[tosinosu]

I am trying to run a molecule test on my vagrant box using ansible local. Just as it is possible to have the below command in a Vagrantfile which runs ansible and all playbooks in the remote machine.

  user.vm.provision "ansible_local" do |ans|
    ans.compatibility_mode = "2.0"
    ans.inventory_path = "path/to/directory/on/remote/machine"
    ans.playbook = "path/to/directory/on/remote/machine"
    ans.verbose = "v"
  end 

The molecule file I am using for the deployment is below but I am getting error.

---
dependency:
  name: galaxy

driver:
  name: vagrant
  provider:
    name: virtualbox
    type: virtualbox

platforms:
  - name: molecule
    box: debian/bookworm64
    instance_raw_config_args:
     - 'vm.synced_folder "/local/directory", "/remote", type: "rsync", disabled: false'
    memory: 2048
    cpus: 2
    config_options:
      ssh.keep_alive: true
      ssh.remote_user: "vagrant"
    interfaces:
      - network_name: private_network
        ip: 10.10.11.12
        auto_config: true
    provision: true
provisioner:
  name: ansible_local
verifier:
  name: ansible

I got the error below after executing molecule converge in the molecule directory. I would like to ask if molecule provides a way of achieving the same purpose as vagrant ansible _local.
