Thanks for filing this issue and sorry you are running into this issue.
Are you still running into this issue?
What version of Jupyter Hub do you have installed?
Can you verify you can log into Jupyter hub via the browser?

lifetooeasy · 2024-02-06T09:28:43Z

@DonJayamanne Unfortunately, I still have this issue I am running jupyterhub 1.5.0 and yes I can log in to jupyterhub.

lifetooeasy · 2024-03-04T09:26:50Z

@DonJayamanne I am running version 2.3.1 of jupyterhub now and still have same issue, do you don't think that the new versions of vscode or vscode-jupyter-hub are the cause of this issue?

lifetooeasy · 2024-03-04T09:27:12Z

could be related to microsoft/vscode-jupyter#39 ?

quantum-byte · 2024-03-27T12:03:19Z

@life
Because i was looking into a similiar issue just now.

Are there any special characters in the Jupyterhub username or what does your Jupyterhub user specific instance url look like ?

DonJayamanne · 2024-03-28T03:07:44Z

I'm having the same problem, I reinstalled using visx and still have the same problem, my username has no special characters and I'm pretty sure I can log in in my browser!

@DonJayamanne vscode can connect to remote server and list the available remote kernels.
When I click on one of them the kernel is enabled BUT when I try to execute a cell I got this:

DonJayamanne · 2024-07-30T10:08:08Z

How have you started Jupyter hub? Is this locally installed?

If so please can you share the details of the versions of Jupyter hub and other packages

lifetooeasy · 2024-07-30T10:55:01Z

I am trying to connect to a remote jupyterhub not locally. It runs jupyterhub version 4.1.5 and jupyterlab 4.2.2.

DonJayamanne · 2024-07-31T06:57:00Z

@lifetooeasy
I think i have a better understanding of the issue now.
Do you have any idea how the remote JupyterHub server has been configured.

Do you just need a user name & password to authenticate against that server when using a regular browser (outside VS Code)?
- Is this using OAuth or some other authentication mechanism?
What details are you providing when you try to connect to this from within VS Code?

lifetooeasy · 2024-08-01T06:30:29Z

@DonJayamanne

outside vscode I am using username/password to authenticate
I am providing the URL of the jupyterhub server + username + token

dorsegal · 2024-08-01T10:03:17Z

I had the same issue Error: '_xsrf' argument missing from POST. took this fix #65 and now I have another error.

Exception while handling messages: TypeError: First argument to DataView constructor must be an ArrayBuffe

DonJayamanne · 2024-08-01T10:07:12Z

@dorsegal you are running into the issue #64

dorsegal · 2024-08-01T10:51:32Z

I tried the work around but I have the same result.

Exception while handling messages: TypeError: First argument to DataView constructor must be an ArrayBuffer

Yefee · 2024-08-07T14:49:40Z

I tried the work around but I have the same result.

Exception while handling messages: TypeError: First argument to DataView constructor must be an ArrayBuffer

This is something I also encountered.

Although I have found a workaround, it is still painful to repeat the process every time.
Follow these steps: 1) Open JupyterHub in your browser and terminate the current kernel. 2) Return to VS Code and click "Restart" at the top of the notebook. 3) Run the notebook again and you've bypassed this error from now on.
For every notebook, you have to repeat this process 😫.

nitzanvolman · 2024-09-22T07:22:53Z

we have this issue as well,
I can confirm this workaround works (pretty annoying)

Cursor Version: 0.40.4
VSCode Version: 1.91.1

JupyterHub Extension Version: v2024.5.1002432242

JupyterLab Version: Version 4.0.12
