ob-ipython-inspect causes tornado to throw "Internal server error"; json.decoder?

[singletS]

Since ipython/jupyter upgrade, ob-ipython-inspect causes "Internal server error". Traceback from the ob-ipython-client-driver buffer suggests a missing/non-escaped character in json.decoder?

Traceback (most recent call last):
  File "/home/anaconda3/lib/python3.5/site-packages/tornado/web.py", line 1401, in _stack_context_handle_exception

Have you tried again with the latest version(s)? This looks more like an IPython/Jupyter issue. ob-ipython-inspect does work with IPython 5.1.0 over here.

Thanks for the update. I'm glad to hear this is working with newer IPython, though I haven't tried it myself (migrated over to the scimax/emacs environment).
