If it doesn’t exist “yet”, I’m fine its property returns '', null, etc
Hello @stdedos,
Yes, this is possible.
You can suppress the callback exception and also prevent_initial_call, however. If you have an input that does exist and an input that doesnt exist, you will have errors.
But … suppress_callback_exceptions is a thing of dash.app? Not clientside_callback?
prevent_initial_call in my very specific case does not help a lot - but I can see how that could help otherwise
It is part of the callback definition, therefore it would also apply to how the renderer works on the client.
I tried suppress_callback_exceptions and I didn’t see much difference. Probably because, also according to docs (I think) it does not suppress issues with “unconnected I/O”.
https://dash.plotly.com/urls#dynamically-create-a-layout-for-multi-page-app-validation might be useful, but that would mean a little too much work right now
If this didnt work, then things like pattern-matching callbacks would fail.
Can you please present the MRE for what isnt working?
