404 error on GET /user/[name]/tree? & No user identified error after successful Hub login

maxatideon · July 20, 2022, 11:15pm

Using a fresh install of JupyterHub 2.3.1. After successful login via the Hub, the single user server seems to spawn correctly, but then throws a 404 error when trying to access the file tree (or anything at all).

The SingleUserNotebookApp has a log entry that says No user identified and I think this may be part of the problem. I can’t figure out what it the root cause.

An interesting datapoint, if I downgrade the version of Jupyterhub to 1.4.0, it works as expected.

Here is the log output:

My config is quite simple…

import os

pjoin = os.path.join
runtime_dir = os.path.join("/tmp/ic-runtime-assets/plain")

c.JupyterHub.cookie_secret_file = pjoin(runtime_dir, "cookie_secret")
c.JupyterHub.db_url = pjoin(runtime_dir, "jupyterhub.sqlite")

c.Spawner.debug = True
c.Spawner.default_url = "/tree"
c.Spawner.notebook_dir = "/home"

Any guidance on how I might fix this would be greatly appreciated.

Hi! How are you running JupyterHub, e.g. are you manually running it as root, are you running it as a systemd service, etc?

What happens if you remove c.Spawner.notebook_dir?

maxatideon · July 21, 2022, 4:42pm

I am running JupyterHub as root in a Docker container. The Jupyterhub is started as a part of the Docker’s ENTRYPOINT script.

Removing c.Spawner.notebook_dir does change the location where the hub tries to start, but the same issue occurs.

I am wondering whether there is an issue with the Hub passing user information to the individual notebook servers?

When I encounter the issue, I note that the end of the SingleUserNotebookApp log lines are like:
(@::ffff:172.18.0.1) 1.16ms whereas when I use 1.4.0 successfully they are like (max@::ffff:172.18.0.1) which is what is at the end of the Hub logs here.

Do you have a full reproducible example, e.g. your Dockerfile and the exact commands you’ve run?

I’m having a quite similar problem. Did you manage to solve it?
In my case, sometimes everything work correctly, and I manage to open the notebook, console or terminal. But others the system hangs. The funny thing is that this situation happens in one login, and in the next everything works well, but in the next one or so it doesn’t work again.
