Ansible 'find' command - print only filenames - module

Question

I am trying to use Ansible find command to delete files with a given pattern. Before executing the delete part, I want to list the files that will be deleted. I want to list only filenames including path. The default debug prints a lot of information
- name: Ansible delete old files from pathslist
find:
paths: "{{ pathslist }}"
patterns:
- "authlog.*"
- "server.log.*"
register: var_log_files_to_delete
- name : get the complete path
set_fact:
files_found_path: "{{ var_log_files_to_delete.files }}"
- debug:
var: files_found_path
This outputs like below
{
"atime": 1607759761.7751443,
"ctime": 1615192802.0948966,
"dev": 66308,
"gid": 0,
"gr_name": "root",
"inode": 158570,
"isblk": false,
"ischr": false,
"isdir": false,
"isfifo": false,
"isgid": false,
"islnk": false,
"isreg": true,
"issock": false,
"isuid": false,
"mode": "0640",
"mtime": 1607675101.0750349,
"nlink": 1,
"path": "/var/log/authlog.87",
"pw_name": "root",
"rgrp": true,
"roth": false,
"rusr": true,
"size": 335501,
"uid": 0,
"wgrp": false,
"woth": false,
"wusr": true,
"xgrp": false,
"xoth": false,
"xusr": false
}
I tried files_found_path: "{{ var_log_files_to_delete.files['path'] }}" but it generates an error.
How can I print only the paths?
Thank you

The Jinja2 filter map as a parameter attribute to transform a list of dict into a list of a specific attribute of each element (https://jinja.palletsprojects.com/en/2.11.x/templates/#map):
- name : get the complete path
set_fact:
files_found_path: "{{ var_log_files_to_delete.files | map(attribute='path') | list }}"
For more complex data extraction, there is the json_query filter (https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#selecting-json-data-json-queries)
