@edan-bainglass thanks for the report. Is it crashing on container startup? Where exactly do you see this trace?

[edan-bainglass]

On container startup

Just provide more context, if I understand correctly from the discussion with @edan-bainglass, he changed to use edge image for his profile and it can not start with the exception above. My guess was some jupyter core package installed in his home folder that cause the conflict. I remember @danielhollas pinned a jupyter package version could that be the cause of the issue?

[danielhollas]

jupyter package version could that be the cause of the issue?

No, I don't think that's the issue. But I believe I saw something similar when i was upgrading the container to the edge image.

@edan-bainglass Can you provide the output of pip list --user in the container?
You're going to have to run the container manually with attached volume, depending on your config, something like (substitute <profile_name> with the name of your profile if you use aiidalab-launch

docker run -v aiidalab_<profile_name>_home:/home/jovyan ghcr.io/aiidalab/full-stack:edge pip list --user

My guess was some jupyter core package installed in his home folder that cause the conflict.

Yes, I'd guess this is likely. Another thing to know is what was the previous version of the image that worked?

[danielhollas]

According to this issue, downgrading or upgrading traitlets might fix this jupyter/notebook#7048

[danielhollas]

It seems that this is caused by traitlets>=5.10.0 . @edan-bainglass can you please confirm what version of traitlets are you running? You should be able to get it working by installing traitlets==5.9.0.

I would also be interested about which version of the image have you been running previously. AFAIK this is not a problem with edge, I see in with latest and also with previous versions, so now I am thoroughly confused as to how this ever worked and why we did not notice it previously???

Ohhh, I found it. 😅 It looks like this issue has been introduced only very recently in aiidalab-widgets-base==2.3.0a1 where I unpinned the traitlets version specifier from ==5.9.0 to ~=5.9, I didn't know that newer versions did not work. I'll put up some PRs to fix this, but in the meantime @edan-bainglass you'll have to reinstall traitlets manually.

EDIT: Here's the PR that introduced this aiidalab/aiidalab-widgets-base#621
This also uncovers a problem with the current tests which clearly did not catch this. The problem is that when running the notebook tests in AWB, we first launch the container, and only then we install AWB. Which means that we don't catch issues that only pop up once the container is restarted. (also related to #477 in this repo)

@danielhollas thanks for taking care of this. Note that it is no longer a concern for me at the moment.

A bit of context - I was exploring Solara for app/widget development, specifically for the QueryBuilder-widget. As it would be part of the widgets base repo, I figured I'd develop in an AiiDAlab container. Solara requires ipywidgets v8.x. Hence, I checked out the full-stack:edge image. Then the above issue occurred. However, in the meantime, I had decided to instead develop in a separate/dedicated repo. Therefore, no longer an issue.

In any case, good we caught this bug. Thanks again @danielhollas, @unkcpz for addressing it.
