I hit this yesterday too.
Sorry to resurrect very old thread but thought I would add that in the end
I wound up with the following syntax (to retrieve a list of conmmit

around items:
- name: collect the commit messages
set_fact:
commit_messages: "{{
build_info.json.changeSet['items']|map(attribute='msg')|list }}"
