Bug Description

When accessing /api/2.0/machines/{system_id}/ I am sometimes receiving a JSON object as a return and am sometimes receiving a pickle object as a return.

http://maas1.lab/MAAS/api/2.0/machines/4y3h7q/

Returned Pickle object: http://paste.ubuntu.com/23217500/

This happened on MAAS Version 2.0.0+bzr5189-0ubuntu1 (16.04.1)

What are you going to make the request? Using curl? If so you should specify an Accept header for application/json.

Good point. However, should we ever return pickles?

@blake

Thanks for the quick response. I am using the python requests module to generate the request. I was not specifying the Accept header for "application/json", I will specify that explicity and see if it happens again.

Specifying Accept header for application/json looks to have fixed the issue. Thank you! I will open a new bug should it happen again.
