Undefined icinga_objects crashes playbook

[C0rn3j]

Worked around/fixed by changing

  when: vars['icinga2_objects'][icinga2_config_host] is not defined

to

  when: vars['icinga2_objects'] is defined and vars['icinga2_objects'][icinga2_config_host] is not defined

TASK [icinga.icinga.icinga2 : collect all config objects in play vars] *****************************************************************************************************************************************************************************************************************************************************
fatal: [agent]: FAILED! => 
    msg: |-
        The task includes an option with an undefined variable. The error was: 'icinga2_objects' is undefined. 'icinga2_objects' is undefined

        The error appears to be in '/root/.ansible/collections/ansible_collections/icinga/icinga/roles/icinga2/tasks/objects.yml': line 8, column 3, but may
        be elsewhere in the file depending on the exact syntax problem.

        The offending line appears to be:


        - name: collect all config objects in play vars
          ^ here
