Error running timer `ein:query-ajax-timeout-callback': (json-readtable-error) while opening notebook list at any server

Description of the problem you have

when I run ein:notebooklist-open I get the error messages

Contacting host: 127.0.0.1:8961 ein: [error] QUERY-AJAX--PARSE-DATA: error from parser ein:json-read error in process filter: eq: JSON readtable error error in process filter: JSON readtable error ein: [error] QUERY-AJAX--PARSE-DATA: error from parser ein:json-read Error running timerein:query-ajax-timeout-callback': (json-readtable-error)`

This is independent to the port number or even URL for that matter

Steps to reproduce the problem

start ipython server
M-x ein:notebooklist-open
Expected output

Given the port, or the URL, I would have expected to see my notebook in a format similar to that of the screenshots here https://github.com/tkf/emacs-ipython-notebook/wiki/Screenshots

Based on the System Info below, I am guessing that my problem is related to the request settings, since I can see websocket, popup, etc...but not request. However, at this stage I do not what to do.

Your EIN configuration (in .emacs.d/init.el or somewhere else)

I have tried unnumbered configurations, but this is how the relevant section of my .emacs file looks (surely, half of it is irrelevant).

;;Ipython Notebook (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/request-0.2.0/") (require 'request) (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/helm-1.6.7/") (require 'helm) (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/company-0.8.9/") (autoload 'company-mode "company" nil t) (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/popup-0.5.2/") (require 'popup) (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/websocket-1.3/") (require 'websocket) (add-to-list 'load-path "/Users/javier/.emacs.d/elpa/ein-0.2.0/") (require 'ein) (require 'cc-mode) ;;(setq ein:use-auto-complete t) ;; Or, to enable "superpack" (a little bit hacky improvements): (setq ein:use-auto-complete-superpack t) `(setq ein:use-smartrep t)``

Your IPython configuration

What is your IPython version? (run ipython --version):

2.2.0

How do you start IPython? (e.g., ipython notebook --port 9999):

ipython notebook

What is your IPython notebook port number or URL?:

http://localhost:8961/notebooks/pnb01.ipynb

Additional information (if any)

I have installed request using elpa, not from here https://github.com/tkf/emacs-request .

This should not matter, right(?)
