I can open the jupyter notebook with chorme successfully but cannot do anything with the errors above

The notebook server works but floods the terminal log with these messages every few seconds.

In addition I notice on refresh of a notebook or jupyter page, I get re-prompted for my token. I'm also seeing this in my log:

[E 13:23:56.741 NotebookApp] Error unpacking user from cookie: Extra data: line 1 column 8 (char 7)

@TheCleric - interesting, we're seeing this too via Binder - linking here in case it's relevant... jupyterhub/binderhub#1622

[wallyhall]

@TheCleric - see my comment here ... have you tried pinning to jupyterlab 3.4.8?

[takluyver]

I just ran into this as well, and installing an older version of jupyter-server (pip install 'jupyter-server<2') made it work. I see there's also a jupyter-server issue: jupyter-server/jupyter_server#1038

[Linusnie]

Same issue here, downgrading jupyter-server didn't work either

edit: not sure why but changing the port from 8888 to 8885 made the warnings go away
