Panel Preview not working: KeyError #7433

Open MarcSkovMadsen opened 1 day ago

MarcSkovMadsen commented 1 day ago

I'm working on upgrading our jupyterhub and Panel. In our existing setup the Jupyter Panel Preview is working. But not in the new setup.

Steps

Check the server logs

Additional Context

I'm told there is also a xrsf cookie issue https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues/3422. I don't know if its related.

philippjfr commented 1 day ago

Reading the code I really struggle to see how this is possible UNLESS the websocket connection takes >30 seconds to open. Can you confirm how quickly this happens?

MarcSkovMadsen commented 1 day ago

Thanks so much for responding. The preview opens and closes the web socket almost instantanously.

MarcSkovMadsen commented 1 day ago

I looked at recent changes in jupyter_server_extension.py

Could any of these two changes cause this on a Jupyterhub where things are running behind a reverse proxy?

MarcSkovMadsen commented 1 day ago

FORGET THIS COMMENT. IF THE EXCEPTIONS ARE RAISED THEN LINE 392 WILL NEVER BE REACHED.

As I see it self.close() must have run for some unknown reason:

Would be nice of the ProtocolErrors where logged.

MarcSkovMadsen commented 1 day ago

Right now my hypothesis is that token/ session_id is not valid due to the xrsf cookie issue https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues/3422 mentioned.

philippjfr commented 1 day ago

I'm fairly certain those are unrelated issues, the token is transmitted as part of the websocket headers so that seems unlikely to be affected by any cookie issues. Also the token clearly can be decoded since it doesn't error on the get_session_id call.

My understanding from reading the issue is that it is in fact a headers issue.

I just do not understand if its causing this issue.

MarcSkovMadsen commented 23 hours ago

FYI. It works locally in a fresh pip install panel jupyterlab environment on my windows laptop:

MarcSkovMadsen commented 18 hours ago

An additional comment is that we've mixed a helm chart v 3.3.8 for installing Jupyterhub App. version 4.1.6 with installing the jupyterhub 5.2.1 python package. We will try to align these.
