This code works with ansible 1.9.4

  • name: Configure user parameters
    template: src={{ lookup(‘first_found’, [ ‘userparameter_’ + item + ‘’ + ansible_pkg_mgr + ‘.j2’, 'userparameter’ + item + ‘.j2’ ]) }} dest=/etc/zabbix/zabbix_agentd.d/userparameter_{{ item }}.conf
    with_items: “{{ zabbixagent_userparameters }}”
    when: zabbixagent_userparameters is defined
    notify:
  • restart zabbix-agent

But not working with 2.0.0.1

What I do wrong ?

the lookup is returning a list, not a string, as a workaround:

template: src={{ lookup('first_found', [ 'userparameter_' + item +
'_' + ansible_pkg_mgr + '.j2', 'userparameter_' + item + '.j2' ])[0]
}}

thank you very much.

is it make any sense that first_found return a list ?
i think that first means that list will always contain 1 element.

looking into that, for most lookups the answer is 'yes', in this case
it can be considered a bug, you should open an issue in github.

fixed in https://github.com/ansible/ansible/pull/14281, will be out in the next releases
