Problem description:

I try to execute the installation command:

ansible-playbook -i inventory/hosts setup.yml --tags=install-all,ensure-matrix-users-created,start

The following error occurs here and unfortunately I could not find anything or everything I tried was unsuccessful.

TASK [galaxy/systemd_service_manager : Ensure systemd is reloaded] *************************************************
s_push: parser stack overflow
fatal: [matrix.<domain>]: FAILED! =>

    The conditional check 'devture_systemd_service_manager_services_list_to_work_with | length > 0' failed. The error was: An unhandled exception occurred while templating '{{ devture_systemd_service_manager_services_list }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: An unhandled exception occurred while templating '{{ devture_systemd_service_manager_services_list_auto + devture_systemd_service_manager_services_list_additional }}'.

    The error appears to be in '/home/ubuntu/matrix-docker-ansible-deploy/roles/galaxy/systemd_service_manager/tasks/restart_specified.yml': line 3, column 3, but may
    be elsewhere in the file depending on the exact syntax problem.

    The offending line appears to be:

    - when: devture_systemd_service_manager_services_list_to_work_with | length > 0
      ^ here
