See the changelog entry about the migration: https://jupyterlab.readthedocs.io/en/stable/getting_started/changelog.html#jupyter-server (in particular, https://jupyter-server.readthedocs.io/en/stable/operators/migrate-from-nbserver.html)

Thanks it really helped !!
I still get the message about the notebook_dir and just renamed it to root_dir in the conf file, fixed the issue.
By chance I founded a command to generate a completely new serverapp config file: jupyter server --generate-config
So I just modified this new one and deleted the notebook_config.

It still have one issue, extensions are loaded but it suggest to move them to jupyter server's extensions path, how I can do that ?

Hello Sid,

Can you run me through exactly what you did please. Ever since I updated anaconda --all I have been getting the following message below when I open Jupyter notebooks and doesn't proceed to go to my notebooks and just keeps saying waiting for localhost?

Here's my issue:

[W 2021-05-12 16:41:48.674 LabApp] 'notebook_dir' has moved from NotebookApp to ServerApp. This config will be passed to ServerApp. Be sure to update your config before our next release.

Hi sorry I changed for vscode since January, but as I can read my self, I executed this "pip uninstall nbdime nbresuse" on cmd

The warning message about min_open_files_limit being None also happens in a brand new installation, created according to the :

Hi, I had the same problem as you and I would like to know how you solved it.

This was fixed in jupyter_server v1.11.1 by jupyter-server/jupyter_server#587. Please upgrade jupyter_server to get the fix.
