Items are overwritten in Task - ansible

Question

We're trying to fill an Palo Alto Object Group with multiple objects.
Our current script does run through all the items in the following line:
static_value: "{{ item[1].addressobjectname|join }}"
But only registers the last object.
For Example:
We have 3 objects in the list. So we expect to add object 1, 2, 3.
Instead the script only registers the 3 and 1 and 2 are overwritten in the process.
How should we fix this?
This is our code:
- name: Create object group
with_nested:
- "{{ tag_firewall# }}"
- "{{ addressobjects }}"
panos_address_group:
provider: "{{ palo_provider }}"
name: "Prisma-Unsecure"
static_value: "{{ item[1].addressobjectname|join }}"
tag: ["ansible_test_tag"]
device_group: "{{ item[0] }}"

Thanks in advance!
As mentioned before we expect all items to be added to the group in stead of the last one in the list.

Answer 1

Hard to say without the precision asked by Vladimir in comments. Meanwhile it looks like you are creating an address group for each addressojects for each firewall definition. My guess at this stage is that the last one wins with the latest address.
Guess again: I believe you want to create one group with all adresses, something like the following (to be tested and adapted with your actual input data):
- name: Create object group
loop: "{{ tag_firewall# }}"
panos_address_group:
provider: "{{ palo_provider }}"
name: "Prisma-Unsecure"
static_value: "{{ addressobjects | map(attribute='addressobjectname') }}"
tag: ["ansible_test_tag"]
device_group: "{{ item }}"

Answer 2

My guess is to remove the join filter. For example,
shell> cat pb.yml
- hosts: localhost
vars:
tag_firewall: [Prod1, Prod2]
addressobjects:
- addressobjectname: [Test-One, Test-Three]
- addressobjectname: [Test-Two, Test-Four]
tasks:
- debug:
msg: |
panos_address_group:
provider: Palo_provider_dict
name: Prisma-Unsecure
static_value: "{{ item.1.addressobjectname }}"
tag: Ansible_test_tag
device_group: "{{ item.0 }}"
description: Created by Ansible automation
commit: false
with_nested:
- "{{ tag_firewall }}"
- "{{ addressobjects }}"
shows the iteration
shell> ansible-playbook pb.yml
