Thanks for reporting this. There's been a lot of changes recently to idom and not all of them have made their way into idom-jupyter just yet. I suspect that's probably the cause.

@rmorshea thanks for the quick response. very strange behavior here.
launching through https://binder.mybinder.ovh/, resulting in https://hub-binder.mybinder.ovh/user/idom-team-idom-jupyter-exdbosus/lab, and the examples work.
launching through https://mybinder.org/, resulting in https://hub.ovh2.mybinder.org/user/idom-team-idom-jupyter-v38662cg/lab, and the examples don't work

[rmorshea]

That's very helpful information. Would have been very hard to find that out on my own.

If you open the debug console on your browser, do you get any interesting tracebacks?

no

For some reason when I launch through https://mybinder.org I end up with instances deployed at https://hub-binder.mybinder.ovh. However, when I deploy via https://ovh2.mybinder.org/ I get redirected to https://hub.ovh2.mybinder.org which, as you explain, results in errors.

[rmorshea]

I have a draft PR to upgrade to the latest widget template and I see similar errors when I deploy that branch, even via https://mybinder.org. Hard to say exactly what's going on at the moment. Will keep digging when I find time though.

even when i use the same link https://binder.mybinder.ovh/ on this repository and my forked version (without changes), this repository works while my forked version results in same error. 😑

I'm unable to reproduce in ovh2 now. I'm also unable to reproduce when testing this out with repo2docker. I'm not really sure what to do here at the moment given that I'm no longer able to reproduce. Will close for now, but please comment if this persists.

[rafaellichen]

@rmorshea can you verify this for me? thanks.
it doesn't work for me even though the code is the same. originally thought it could be js cache issue, but same problem persists under incognito mode.

[rmorshea]

Ok, I just double checked and I think I was looking at my open PR when testing things out. I can confirm that main is broken. However, my changes in #25 seem to fix things.

[rmorshea]

I'll merge that PR and cut a release shortly.

[rmorshea]

Ok, the PR has been merged. It would be great to get confirmation that everything works on your end before I do a release.

yes, can confirm it works even for my forked version of this repo now. thanks.
