Screenshot/Video

Firefox ( also tested with new installation / different machine / vm etc.):

Other Browsers I tested (Opera, Chrome, Vivaldi, in this screenshot Edge)

Does this issue happen in VS Code or GitHub Codespaces?

• [X] I cannot reproduce this in VS Code.
• [X] I cannot reproduce this in GitHub Codespaces.

Are you accessing code-server over HTTPS?

• [X] I am using HTTPS.

yeah this is happening with 4.5.0 but not 4.4.0 in Chrome, Safari, and Firefox. I just tried both side-by-side with fresh docker-based installs. for what it's worth the 4.5.0 version also carries with it newer versions of the Jupyter extension. I tried downgrading to v2022.3.1000901801 with 4.5.0 but it didn't fix the problem. The Terminal also didn't work with 4.5.0.

[Emporea]

Can confirm that this bug doesn't occur on 4.4.0

But I dont get how it can only affect one browser.

[jsjoeio]

Is this a duplicate of https://github.com/coder/code-server/issues/5335? Or are they somehow related?

[Emporea]

@jsjoeio I don't know how they are related (atleast they share downgrading to 4.4.0 as a workaround), but this is definitly not a duplicate.

[jsjoeio]

Ah got it. Okay We'll investigate!

[mathematicalmichael]

@Emporea for me it is impacting all browsers I have installed. @jsjoeio thank you very much for investigating! 4.4.0 is the first version where Jupyter notebooks actually function and it makes me so happy to finally be able to use code-server exclusively for my work.

[benz0li]

Is this a duplicate of #5335?

No.

Or are they somehow related?

No, they are not.

[jsjoeio]

@mathematicalmichael hooray! that's great to hear.

We really need to add some e2e tests for Jupyter. I'm going to add this to the next sprint.

[benz0li]

FYI code-server 4.5.1 is working fine with [email protected] and [email protected].

[benz0li]

@Emporea @mathematicalmichael Please test again with code-server 4.5.1.

Most probably related to https://github.com/coder/code-server/issues/5321.

[jsjoeio]

Hooray! Thank you @benz0li for testing and confirming!

[Emporea]

~Its working with 4.5.1. Thanks.~

[Emporea]

Wait. Its not. huh.. It opened one time, but had the same bug after that again.

[benz0li]

@Emporea Use Firefox to log into https://demo.jupyter.b-data.ch.

If it does not work, it might be a problem with your Firefox settings or extensions.

[Emporea]

I removed the docker container and recreated it and now its working so far. I hope it stays that way, cause i did that already several times, so it seems inconsistent for me. But thanks for solving it in theory.

[benz0li]

But thanks for solving it in theory.

It runs just smoothly [also in practice] at https://demo.jupyter.b-data.ch 😉.

[Emporea]

Sometimes its working. Sometimes not. With 4.4.0 its working everytime.

[jsjoeio]

Use Firefox to log into https://demo.jupyter.b-data.ch/.

@Emporea are you seeing the same results here?

[Emporea]

The demo is also not working.

[benz0li]

The demo is also not working.

@Emporea It is a problem with your Firefox settings or extensions, then.

[Emporea]

Whatever. The inconsistency makes it super hard to understand and to describe. You probably think i am a noob. Well I stay on 4.4.0 for a while and see if the inconsistencies also occur there.

[benz0li]

See also https://github.com/coder/code-server/issues/4777#issuecomment-1023511535 about private/incognito mode [and possibly opening a folder (File > Open Folder...) before opening a Jupyter notebook].

[jsjoeio]

@Emporea not a noob! Just trying to help. Any other information you can share is helpful, otherwise I will try reproducing

[mathematicalmichael]

I have a containerized environment that launches in the cloud (free) via binder here: https://mybinder.org/v2/gh/ml-starter-packs/microservice-workshop/main?urlpath=vscode/ (Dockerfile).

latest commit pins codeserver to 4.5.1, and I found

• [ ] terminal functioning as expected
• [ ] notebooks working

[mathematicalmichael]

hm... unfortunately I got a weird error trying to even install extensions in the first place

don't know if it's related... but I tried 4.4.0 yesterday and it was fine. I'll try rolling back the commit and seeing if the behavior occurs again (is it MS-extensions related or code-server related?)

[jsjoeio]

Weird, I'm seeing the same 🤔 open-vsx was down yesterday. maybe related?

Yeah, when i search for any extension i see the same error:

Looking at the network requests, it appears to be returning a 503

[mathematicalmichael]

oh okay, so not related to code-server?

sidenote: i love that you can reproduce the errors on your own thanks to binder... what an age we live in.

thank you so much for looking into it!

[jsjoeio]

oh okay, so not related to code-server?

correct! @benz0li opened an issue upstream: https://github.com/eclipse/openvsx/issues/497

sidenote: i love that you can reproduce the errors on your own thanks to binder... what an age we live in.

right?! crazy! though props to you for giving me the binder link to be able to reproduce so easily 🙌🏼

[Emporea]

4.5.1 still only works occasionally regarding the "jupyterlab notebook not rendering" 4.4.0 works everytime.

It cant be my firefox alone.

[jsjoeio]

I'm on 4.5.1 on macOS and I cannot reproduce 😢

This looks like the exact same issue upstream, right?

https://github.com/microsoft/vscode/issues/132102

Maybe worth dropping a comment on that.
