Cluster config update : error on enable maintenance mode task

[oaitmoulid]

When adding a custom cluster configuration like this :

redpanda:
  cluster:
    auto_create_topics_enabled: true
    data_transforms_enabled: true
    default_topic_replications: 3

playbook fails at enabling the maintenance mode :

TASK [redpanda.cluster.redpanda_broker : Enable Maintenance Mode] ***********************************************************************************************************************************************
task path: /opt/ansible_core/add-ons/collections/ansible_collections/redpanda/cluster/roles/redpanda_broker/tasks/safe-restart.yml:6
fatal: [vm-redpanda-dif-prod-pau-01]: FAILED! => {"msg": "The conditional check 'ansible_play_hosts > 1' failed. The error was: Unexpected templating type error occurred on ({% if ansible_play_hosts > 1 %} True {% else %} False {% endif %}): '>' not supported between instances of 'list' and 'int'. '>' not supported between instances of 'list' and 'int'\n\nThe error appears to be in '/opt/ansible_core/add-ons/collections/ansible_collections/redpanda/cluster/roles/redpanda_broker/tasks/safe-restart.yml': line 6, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n#\n- name: Enable Maintenance Mode\n  ^ here\n"}

Suggested correction : just add " | length " to get the correct value of number of nodes, for example :

- name: Enable Maintenance Mode
  ansible.builtin.command:
    cmd: rpk cluster maintenance enable {{ node_id }} --wait {{ redpanda_rpk_opts }}
  no_log: "{{ redpanda_broker_no_log }}"
  when:
    - restart_required
    - inventory_hostname == cluster_host
    - ansible_play_hosts | length > 1
