Ansible: Can't render JSON in Ansible and POST via uri module

Created on 26 Nov 2015 · 3Comments · Source: ansible/ansible

Issue Type: Bug Report
Ansible Version: 1.9.4
Environment: OSX 10.11.1

Summary: Using lookup to render a template that gets passed into the uri module's body parameter does not work. It throws an TypeError: unhashable type error. I opened a StackOverflow question about this, and thought it made sense to post it here as well.

Steps To Reproduce:

Run this task:

- name: Post
  uri:
    url: https://hooks.slack.com/endpoint
    method: POST
    return_content: no
    HEADER_Content-Type: "application/json"
    body: "{{ lookup('template', '../templates/my.json.j2', convert_data=False) }}"

with this in my.json.j2:

{
  "channel": "chatops",
  "username": "Deploy",
  "text": "TEST Deploy!",
  "icon_emoji": ":ghost:"
}

Folding the JSON into a single line within the template has the same effect. Piping the lookup response through to_json also does not work. Taking the folded JSON and using it _directly_ in the play does work, however.

Expected result: proper JSON sent to endpoint

Actual result: TypeError: unhashable type error; also, in certain circumstances, a not valid JSON error is returned by the endpoint, which indicates that the data is not being sent properly.

This was fixed in 2.0: just add _body_format: json_ to uri module (and remove _convert_data=False_)
Also, you don't have to set the Content-Type header yourself when setting body_format to json.
