How to access nested variable using debug module in Ansible

I use this task to access files:

- name: Find logs files
  find:
    paths: /var/log/
    patterns: "*.log"
    recurse: yes
    register: list_matched

- debug:
    var: list_matched.files

Output is:

ok: [127.0.0.1] => {
    "changed": false,
    "examined": 17,
    "files": [
        {
            "atime": 1576496687.5594354,
            "ctime": 1576496687.5594354,
            "dev": 2049,
            "gid": 0,
            "gr_name": "root",
            "inode": 922589,
            "isblk": false,
            "ischr": false,
            "isdir": false,
            "isfifo": false,
            "isgid": false,
            "islnk": false,
            "isreg": true,
            "issock": false,
            "isuid": false,
            "mode": "",
            "mtime": ,
            "nlink": 1,
            "path": "/var/log/mikrotik/mikrotik.log",
            "pw_name": "root",
            "rgrp": true,
            "roth": true,
            "rusr": true,
            "size": 0,
            "uid": 0,
            "wgrp": false,
            "woth": false,
            "wusr": true,
            "xgrp": false,
            "xoth": false,
            "xusr": false
        },

How can I get path parameter? I was trying also something like this:

- debug:
    var: list_matched.files.path

But an error occured:

ok: [127.0.0.1] => {
    "files_matched.path": "VARIABLE IS NOT DEFINED!: 'dict object' has no attribute 'path'"

I want to capture path parameter, but no idea how. It was also hard to find some information about this nested debugging case.

There is an open bracket "[" after "files:" so you need to go that position on the array before going to path.

Try:

var: list_matched.files[0].path

Or:

var: list_matched.files[0]["path"]

To answer the comment, "how should I use it when I get more paths?" try getting the length of the array of "list_matched.files" and looping through it like this:

many_paths = []
for i in range(len(list_matched.files)):
    print(list_matched.files[i].path)
    many_paths.append(list_matched.files[i].path)

print(many_paths)

Maybe you want to save them into an array of paths.

Find returns a dict of values, so you must iterate over the list.

- name: Show file paths
  debug:
    msg: "{{ item.path }}"
  with_items: "{{ list_matched.files }}"
