run with_items loop using python api.

for a bigger project we are interfacing ansible with python using the python api.

however I am not able to run the debug module using a with_items loop.
the purpose is to find/report and delete the files found on remote systems.

play_source = dict(
name=“Ansible Play”,
hosts=‘all’,
gather_facts=‘no’,
vars=dict(sudo_content=sudoers_content),
tasks=[
dict(action=dict(module=‘find’,
file_type=‘file’,
paths = ‘/etc’,
age= ‘14d’,
use_regex = ‘True’,
patterns=‘sudoers(?=\.).*’), register=‘output’),
dict(action=dict(module=‘debug’, args=dict(msg=‘{{ item.path}}’), with_items=‘{{ output.files}}’))

]
)

this executes fine the files are found but the debug task fails due to item variable is undefined.

fatal: [vm]: FAILED! =>
msg: ‘The task includes an option with an undefined variable. The error was: ‘‘item’’ is undefined’

how can i make the loop work?

thanks
