Jim Gu 5839f07e0f yaml callback fails on python3 ... When the URI module returns complex JSON objects, the YAML callback fails while trying to represent these objects. The problem arises because the filter method returns an iterator in Python 3, rather than a str object. Therefore, the str method expandtabs() is not available, and the callback fails with the following error: [WARNING]: Failure using method (v2_runner_on_failed) in callback plugin (<ansible.plugins.callback.yaml.CallbackModule object at 0x7f7c7ed8aa20>): 'filter' object has no attribute 'expandtabs' Issue can be replicated by running this playbook: - hosts: localhost gather_facts: false tasks: - uri: url: https://jsonplaceholder.typicode.com/posts ansible-playbook tmp.yml -v		2018-04-02 11:41:00 -04:00
