json query question

Forgive the noob question. I am new to Ansible. I am attempting to filter the json results of my playbook to only get specific information. Looking at the Ansible documentation, it is possible using community.general.json_query. It appears to work on some of the data but I am unable to come up with the correct syntax for what I need. Below is some sample output along with a snippet of my code. Please help me with the correct syntax. Thanks!

I am trying to get only the value of “author”.

My code snippet:

  • name:

ansible.builtin.debug:
var: item
loop: “{{ results | community.general.json_query(‘json.body[*].book_details’) }}”

Sample json output:

“ansible_loop_var”: “item”,
“item”: {
“asterisk”: 0,
“bestsellers_date”: “2016-12-31”,
“book_details”: [
