Actual behavior

The Pluto Notebook interface doesn't work properly, and it seems to be failing when loading different components:

I also get 500 : Internal Server Error when trying to create new Pluto notebooks, The behavior matches the one seen in this issue.

When I click the Pluto Notebook link in the Launcher, I also get variants of the following log message:

Latest Docker version

• I've updated my Docker version to the latest available, and the issue still persists

[mathbunnyru]

Thanks for creating an issue!

docker run -it --rm -p 8888:8888 --pull always quay.io/jupyter/datascience-notebook:2023-10-23 also gives you an error, right?
I want to make sure the problem has nothing to do with JupyterHub, mounts, and your custom config.

[andreasskeidsvoll]

Thank you for the quick response! I first encountered the problem on Kubernetes based-Rocky Linux cluster, but the same issue also occurs on my laptop with Ubuntu 22.04. I had to add always after the command you suggested to make it work. When I did, I encountered the same issue as before, with the following output from the container (the signal (4.2): Illegal instruction error repeats after the HTTP errors):

[taylorgibson]

I'm seeing this same issue, but only when running on docker via Windows WSL2. The image works perfectly fine on my Macbook Pro (M1).

[mathbunnyru]

Works fine on my M2 MacBook Air too.
Most likely onle x86_64 issue is affected.

[taylorgibson]

Not sure if helpful, but when creating a Jupyter Notebook with a Julia kernel, the following error appears in the logs:

Code seems to execute without issue in the notebook. I don't see this error message in the logs when Pluto loads correctly on my M1 system.

[mathbunnyru]

@yuvipanda I think you have some experience with Julia and Pluto, could you please take a look here?

[mathbunnyru]

@andreasskeidsvoll I know it's not a solution for the issue, but could you please check the issue persists in the latest image?
As far as I remember, the issue was quite spurious, so newer images might work.

[andreasskeidsvoll]

@mathbunnyru For the newest x86 (quay.io/jupyter/datascience-notebook:x86_64-2023-11-07) and multiarch (quay.io/jupyter/datascience-notebook:2023-11-07) images on my laptop, I get the following warnings and errors after clicking the Pluto Notebook link and waiting for about a minute:

together with a 500 : Internal Server Error in the tab that gets opened in my browser. However, Pluto seems to work when following the link again after about five minutes after the first attempt. It's a bit hard to know exactly what happens, as nothing shows up in the logs, but, maybe the Pluto startup is just very slow on my system (which is a decent x86 laptop from 2020 with Ubuntu) while there is a request timeout of about a minute and the startup progress is not shown anywhere?

Note that I still get the following error the first time a new notebook is created inside Pluto, but the error resolves itself:

Also, notebooks created in previous runs of Pluto still show up in the Pluto interface, but these notebooks seem to be missing from the container as I get the following error when trying to enter any of them:

Can't find a file here

Please check whether /opt/julia/pluto_notebooks/notebook_name.jl exists.

I also can't see any way of removing these dysfunctional notebook links in Pluto, but this is perhaps an issue with Pluto and not just the docker-stacks image in particular...

[yuvipanda]

I'm going to have to try figure out how to run these properly on x86 and then can try to repro these (currently only have an ARM mac)

[mathbunnyru]

I almost forgot - docker on Mac (I have M2 mac) allows to run x86_64 images.

For example: docker run -it --rm -p 8888:8888 quay.io/jupyter/datascience-notebook:x86_64-2023-11-07will work and will pull x86_64 image (this tag is not multi-arch).

I also got 500 errors a few times when I launch Pluto from Launcher.
But after a few tries pluto starts and works fine for me.
So, yeah, x86_64 Linux image works better on aarch64 M2 Mac rather then on x86_64 Linux.
When I press Ctrl+C though, I get Segmentation fault though.

If I run aarch64 image, Pluto starts in approximately 45 seconds.

Also, notebooks created in previous runs of Pluto still show up in the Pluto interface

I have this problem too, even with no mounts and after running images for different archs.
Pluto probably stores this information as a cookie in the browser.
The private tab doesn't show missing notebooks.
I think this is a minor problem and is definitely part of Pluto (not docker images).

[yuvipanda]

@andreasskeidsvoll can you tell me what happens if you just load a terminal (instead of pluto) and run the following:

julia --optimize=0 -e            "import Pluto; Pluto.run(host=\"0.0.0.0\", port=8888, launch_browser=false, require
_secret_for_open_links=false, require_secret_for_access=false)"

I tried this on an x86 container, and at least it didn't segfault! I couldn't access anything in a browser yet (my machine is being wonky about port forwarding :(), but can you tell me if this command already segfaults for you?
