(websocket): in callback `on-close': Wrong type argument: arrayp, nil

cthorey commented 10 years ago

Check list

[ ] I read "Avoid standard Emacs traps" section in https://github.com/tkf/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
[ ] I checked that IPython works with the browser interface.
[ ] I checked that the problem was not due to badly compiled files. Removing *.elc files from source directory of EIN and its dependencies did not solve the problem.
[ ] I checked that the libraries are loaded from intended place. (You can check the location in the "System info" section below)
Description of the problem you have

I can start the notebook but when it opens, I got this error with

Error (websocket): in callback on-open': Cannot send message to a closed websocket: cl-struct-websocket-frame, text, "{\"header\":{\"msg_id\":\"32f22d3b-dca1-492f-afc4-1c7470366eb1\", \"username\":\"username\", \"session\":\"4722f4f4-f027-4ce2-be93-14ac8af3e3b8\", \"msg_type\":\"execute_request\"}, \"metadata\":{}, \"content\":{\"code\":\"__import__('sys').stdout.write(__import__('os').getcwd())\", \"silent\":true, \"user_variables\":[], \"user_expressions\":{}, \"allow_stdin\":false}, \"parent_header\":{}}", nil, t Error (websocket): in callbackon-open': Wrong type argument: arrayp, nil

Each time a compile a cell, i got the same error.

In ipython, i got an error as well :

2014-06-25 11:06:37.471 [NotebookApp] WARNING | Cross Origin WebSocket Attempt. 2014-06-25 11:06:37.471 [tornado.application] ERROR | Uncaught exception in /kernels/587835ea-d394-4367-bdb8-63c22e5511c2/shell

Steps to reproduce the problem

ein:notebooklist-open
open a notebook
"Error (websocket): in callback `on-close': Wrong type argument: arrayp, nil"
Expected output

Run the cell in the notebook

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

Same problem with zeroein.el ( is not coming from the configuration)

Your IPython configuration

What is your IPython version? (run ipython --version):1.2.1
How do you start IPython? (e.g., ipython notebook --port 9999): ipython notebook
What is your IPython notebook port number or URL?: 8888
Additional information (if any)

Try with different port, no improvment

There are a few other threads about this issue. Here's one quick fix that requires a small patch to ipython: http://stackoverflow.com/questions/22202182/error-on-websocket-when-try-to-use-ipython-notebook-in-emacs

Thanks, the workaround works indeed. I close the issue
