Почему Ansible падает на ошибку UnicodeDecodeError из за русской переменой

Имеем Ubuntu Server 18.04 и Ansible 2.9.

Подскажите пожалуйста, отчего Ansible При выполнении playbook падает на ошибку:

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 14: ordinal not in range(128)

Сам плэйбук:

- name: Container present
  docker_container:
    name: ubuntu-server
    state: started
    image: "{{ DOCKER_REGISTRY }}/ubuntu:{{ IMAGE_VERSION }}"
    restart_policy: always
    ports:
      - "7017:7017"
    command: "{{ command }}"
    env:
      Some_var: "русcкий текст убийца"
     
     volumes:
       - "/opt/:/opt/"
     networks:
      - name: "{{ DOCKER_NET }}"
  become: yes

Методом научного тыка выяснил что проблема в наличии переменной содержащей русский текст. Но неужели нельзя использовать переменные содержащие русский текст? В документации ничего такого найти не удалось.
