Ansible: Debug and iteration

[Jegan A]

Hello Team,

        I am trying to iteration register value and print that value using debug but I unable to achieve the result which I want to get it. Below is the register value in that I like to get value of "lifecycle_state" using debug. Could you please someone help me on this.

Playbook part:

       - debug: var="{{ item }}"
         with_items:  result_1.volume_attachments

Register result:

ok: [localhost] => (item=result_1.volume_attachments) => {
    "ansible_loop_var": "item",
    "item": "result_1.volume_attachments",
    "result_1.volume_attachments": [
        {
            "attachment_type": "iscsi",
            "availability_domain": "xxxxxxxxx",
            "chap_secret": null,
            "chap_username": null,
            "compartment_id": "xxxxxxxxxxx",
            "device": null,
            "display_name": "xxxxxxxxx",
            "id": "xxxxxxxxxxx",
            "instance_id": "xxxxxx",
            "ipv4": "xxxxx",
            "iqn": "xxxxxxxxxxxx",
            "is_pv_encryption_in_transit_enabled": false,
            "is_read_only": false,
            "lifecycle_state": "ATTACHED",
            "port": 3260,
            "time_created": "xxxxxxxx",
            "volume_id": "xxxxxxxxxxx"
        }
    ]
}

The first 2 lines of the debug output explain what's going on

"ansible_loop_var": "item",
"item": "result_1.volume_attachments",

The list 'result_1.volume_attachments' is not expanded in the 'with_items'
statement and is submitted as 'item' to debug. Then the list is expanded
var="{{ item }}".

To print the 'lifecycle_state' attribute of the items in the list try

- debug:
var: item.lifecycle_state
loop: "{{ result_1.volume_attachments }}"

Notes:
* Use 'loop' instead of with_*
https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.5.html#migrating-from-with-x-to-loop
* Expand the the variable "{{ result_1.volume_attachments }}" in the 'loop'
to iterate the items of the list
https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#using-variables-with-jinja2
* In 'debug' the parameter 'var' is expanded by default
