Invalid argument 3 of operation

[isaaczhou]

Hi try to run it within the ubuntu subsystem on windows 10, got the following error. Looks like it's an lisp error. Any suggestion where it might go wrong? Thanks.

Debugger entered--Lisp error: (error "Invalid argument 3 of operation `call-process-region'")call-process-region("my_list = [1,2,3,4,5]\nmy_list" nil nil nil t nil "--" "/home/isaac/.emacs.d/elpa/ob-ipython-20171203.126/client.py" "--conn-file" "no$apply(call-process-region "my_list = [1,2,3,4,5]\nmy_list" nil nil nil t nil ("--" "/home/isaac/.emacs.d/elpa/ob-ipython-20171203.126/client.py" "--conn-fi$ob-ipython--execute-request("my_list = [1,2,3,4,5]\nmy_list" "none")ob-ipython--execute-sync("my_list = [1,2,3,4,5]\nmy_list" ((:colname-names) (:rowname-names) (:result-params "replace") (:result-type . value) (:results . $org-babel-execute:ipython("my_list = [1,2,3,4,5]\nmy_list" ((:colname-names) (:rowname-names) (:result-params "replace") (:result-type . value) (:results .$org-babel-execute-src-block(nil ("ipython" "my_list = [1,2,3,4,5]\nmy_list" ((:colname-names) (:rowname-names) (:result-params "replace") (:result-type . v$org-ctrl-c-ctrl-c(nil)call-interactively(org-ctrl-c-ctrl-c nil nil)command-execute(org-ctrl-c-ctrl-c)

I have the same error on the Windows 10 ubuntu subsystem:

From the error above, the text is being sent to nil, not to the jupyter kernel.

I also notice that the ob-ipython-kernel-default buffer displays the jupyter console prompt, which I certainly don't remember from running ob-ipython on Mac.

@isaaczhou What is python-shell-interpreter set to for you? (locate-file python-shell-interpreter exec-path) returned nil for me, and I realized I had an error in my .emacs.
