[api] Django restframework 3.3.x update will affect experiment queueing
In my installation with this version of rest framework, I can no longer queue a configured experiment (i.e., click on the "Save" button). Downgrading to 3.2.x makes it work again.
The error caught by the web UI is: Could not read request body (experiments/api.py, line 137) which generates a 400 error.
After inspection, it seems the request is read before entering the our API function. Putting a traceback printout on django/http/request.py read(), shows me the following stack:
