I’ve got an Ansible playbook I’m using to do SNMP user operations on FortiGates using the with_subelements module. I tried using a loop, but that was exhibiting some very bizarre behavior (outlined in another question here). For some reason, I can’t seem to get it to parse and execute properly. You can see the JSON info in the console error outputs where “meta” is the top level element. Do I need to convert the JSON data into a different format? Am I using the wrong syntax? Is what I’m trying to do just not going to work this way?
This is running on RHEL 9.4, Ansible 9.7, and Python 3.11.7. host_pinned is the strategy.
The code is pretty straightforward. It first does an API call to get all the SNMP user info. Then, it should use with_subelements to go through the output and remove any SNMP users not matching the conditional, i.e. standard users.
PLAYBOOK #1:
- name: Gather SNMP info
fortinet.fortios.fortios_json_generic:
vdom: "root"
json_generic:
method: "GET"
path: "/api/v2/cmdb/system.snmp/user"
register: snmp_output
- name: Remove non-standard usernames from FortiGate devices
fortinet.fortios.fortios_system_snmp_user:
vdom: "root"
state: "absent"
system_snmp_user:
name: "{{ item.1 }}"
with_subelements:
- "{{ snmp_output | default([]) }}"
- "{{ meta.results.name }}"
when:
- item.1 != "test1"
- item.1 != "test2"
This code yields the below output and corresponding error. Note how the error message starts flowing into the task before it, which may or may not be the console being weird though this behavior has been consistent.

The conditional check 'item.1 != "test1"' failed. The error was: error while evaluating conditional (item.1 != "test1"): 'item' is undefined. 'item' is undefined
The error appears to be in '/home/svc-acct/_work/7/s/ansible/import_tasks/FortiOS_snmp_update-task.yml': line 61, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
