"Exception while handling messages: TypeError: First argument to DataView constructor must be an ArrayBuffer" on multiple actions

BCutlerSparkNZ commented 2 months ago

It looks like the latest version of this extension is having trouble handling WS messages from a remote JH server.

The exceptions appear in the Jupyter extension logs - but the issue seems to be caused by the latest version of this JupyterHub extension. Reverting to the previous version resolves the issue.

Environment data

VS Code version: 1.92.2
Jupyter Extension version (available under the Extensions sidebar): v2024.7.0
JupyterHub Extension version (available under the Extensions sidebar): v2024.5.1002432242
Python Extension version (available under the Extensions sidebar): v2024.12.3
OS (Windows | Mac | Linux distro) and version: MacOS 14.4
Python and/or Anaconda version: 3.11
Type of virtual environment used (N/A | venv | virtualenv | conda | ...): N/A
Jupyter server running: Remote

Expected behaviour

Able to:

Run code cells
Restart Kernel
Potentially other actions not tested/found

Actual behaviour

Actions never complete, and a number of Error logs are seen in Jupyter Extension logs.

Steps to reproduce:

Create a new notebook in VS Code
Select a kernel from a remote JH server using the kernel picker (succeeds)
Run a code cell (in this case a simple import os) - cell never completes running, sits with a "clock" icon
Hit "Restart" kernel button - info notification appears with message "Restarting Kernel : Python 3 (ipykernel)" and never closes.

Logs

Logs are from the Jupyter Extension.

I just ran into the exact same issue today. Notebooks that were previously working weren't working today. Even a simple hello world. I could not execute a cell. When observing the logs, I also noticed the [error] Exception while handling messages: TypeError: First argument to DataView constructor must be an ArrayBuffer error.

After a lot of troubleshooting and failing, I found that reverting the extension to version v2023.10.1003012305 solved the problem.

(looks like https://github.com/microsoft/vscode-jupyter-hub/issues/68 might be a duplicate)

KrisCien commented 2 months ago

Same here looks like regression in newest version, reverting to version v2023.10.1003012305 solves the the problem.

DonJayamanne commented 3 weeks ago

This should now be fixed in the latest pre-release version of the Jupyter extension. Closing as fixed, if the problem still persists, please feel free to file an issue and I'll look into that. Please try installing the latest version of Jupyter extension 2024.10.*

nitzanvolman commented 4 days ago

When using the pre-release, i wasn't able to connect to my server at all - so i can't confirm this fix. (but seems to be a different issue)

reverting to version v2023.10.1003012305 seems to solve the issue for me as well.

alastairtree commented 1 day ago

I got the same errors when connecting to server running Version 0.35.5 of JupyterLab. Only reverting to v2023.10* versions fixed the issue.
