Error is coming from tornado, but I’m not sure is it tornado or jupyter-notebook issue. Any help about this problem would be awesome!

I fixed by changing my config file. It has some error, after I reset the config file and re-check it is all fixed.

Yes, it’s fine. I changed my .jupyter/jupyter_notebook_config.py inside my home replacing highlevel word with levelname around line 15 (in a unmodified file). If you need to create from scratch this file you can use jupyter lab --create-config command.
