Is there any way to catch exceptions raised during rendering?
When an exception is raised during rendering, Solara displays its traceback as a plain text instead of a page layout. Is it possible to catch such exception and show its traceback in a component on a page? Something like React error boundary would be really helpful here.

Good question, and there is an example at https://solara.dev/documentation/api/hooks/use_exception but that is broken (we'll need to look into that).
I have a working example here, with a comment about a bug in reacton, I hope this helps you: https://app.py.cafe/snippet/solara/v1?projectId=htcps_fmjs

Thank you! I experimented with that a bit and it seems that function components are working too:

Nice, did you find a pattern in it? When it works and when it does not?
It is strange, but replacing
solara.VBox() with rv.Html(tag="div") fixes the use_exception example
