See http://pastebin.com/QWSu641w for the testing playbook I've been using.

Basically, I have several vars that I need to place inside a json string.

The output should look something like:

{"indices": "testlogstash-2014.04.14","ignore_unavailable": "true","include_global_state": false,"partial": true}

Vars are not evaluated unless you use double quotes, and if I use single quotes, like 'indices', the json is invalid. Which means I should escape the appropriate double quotes. Unfortunately, ansible still returns a syntax error.

ERROR: Syntax Error while loading YAML script, apply.yml
Note: The error may actually appear before this position: line 16, column 29
- name: debug stuff
debug: msg="{\"indices\": \"{{ esmaintenance_indexPrefix }}{{ yesterday.stdout }}\",\"ignore_unavailable\": true,\"include_global_state\": false,\"partial\": true}"
^
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"

So, I'm rather stuck...

Any suggestions?
