Hi everyone,
I have opened this 'thread' to show an error than I am getting with ansible
ecs_* modules ( Amazon Elastic Container Service ). First, my server
details:
CentOS 7.2.1511
Python 2.7.5
ansible 2.1.0.0
I begin to take this error executing ECS task definition through module
ecs_taskdefinition:
An exception occurred during task execution. To see the full traceback, use
-vvv. The error was: ValueError: No JSON object could be decoded
fatal: [localhost]: FAILED! => {"changed": false, "failed": true,

This was a VMWare virtualized server with CentOS 7, as I tryed same script
in a VPS server with same CentOS 7 version, and the script executed OK.
Later I tried several Linux distros, such as Ubuntu 14, Ubuntu 16 and Arch,
getting same error.
Doing some debugging, I saw the script crashed here:

Later, I saw that crashing system was using 'subprocess.py' coming with
default python, while working system had this instead:
/usr/lib/python2.7/site-packages/kitchen/pycompat24/subprocess.py
/usr/lib/python2.7/site-packages/kitchen/pycompat24/subprocess.pyc
/usr/lib/python2.7/site-packages/kitchen/pycompat24/subprocess.pyo
/usr/lib/python2.7/site-packages/kitchen/pycompat27/subprocess/_subprocess.py
/usr/lib/python2.7/site-packages/kitchen/pycompat27/subprocess/_subprocess.pyc
/usr/lib/python2.7/site-packages/kitchen/pycompat27/subprocess/_subprocess.pyo
I tried installing a new Centos 7 machine, and configuring python to work
with the libraries above, but it doesn't take effect.
Now I have no more ideas to make it work, ¿could anyone help me or is
getting the same error?
Best regards
