Description

I am getting the following:

    Traceback (most recent call last):
      File "/home/martinrenou/micromamba/envs/glue-lab/lib/python3.11/site-packages/tornado/websocket.py", line 944, in _accept_connection

                 ~~~~^^^^^^^^^^^^
    KeyError: 'metadata'

Leading to not being able to open the Notebook (it's an empty area on Jupyterlab)
