Hello all,
I hope we are all well in this trying period across the world.
I am to debug an ACI query to display a simple output, but having trouble
getting the correct syntax to provide the output I desire.
My Ansible Script to query a BD & the debug script to *try *to display just
the subnet information.
- name: ACI Subnet query allocated to BD
hosts: apics
gather_facts: no
tasks:
- name: Query BD
aci_bd_subnet:
host: "{{ ansible_host }}"
username: "{{ ansible_user }}"
password: "{{ ansible_password }}"
validate_certs: no
tenant: tn_TRAINER
state: query
register: subnet_output
- name: Debug message for ACI
debug:
msg: "Subnet : {{subnet_output.current}}"
Now my output:
$ ansible-playbook aci_debug.yml
PLAY [ACI Subnet query allocated to BD]

I am trying to get a debug message similar to:
msg: 'Subnet : 192.168.101.1/24'
But I can't work out how to do that from the registered output
I have tried:
- name: Debug message for ACI
debug:
msg: "Subnet : {{subnet_output.current.fvTenant}}"
But get this meesage:
$ ansible-playbook aci_debug.yml
PLAY [ACI Subnet query allocated to BD]

TASK [Query BD]
************************************************************************************************************************************************************************************************************************

TASK [Debug message for ACI]
***********************************************************************************************************************************************************************************************************
fatal: [apic2]: FAILED! =>
msg: |-
The task includes an option with an undefined variable. The error was:
'list
object' has no attribute 'fvTenant'
The error appears to be in
'/home/network_automation/trainer/aci_debug.yml': line 21, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: Debug message for ACI
^ here

I have tried to find an answer but not managed to get a solution. Anyone
got some guidance?
Thanks & be safe
