Digging deeper in the router navigation code shows an com.vaadin.flow.router.NotFoundException with the exact cause (missing resource) but this is never exposed within the StackTrace

Maybe this can be enhanced to get the error cause at least in the console?!

Happens with 10.0.0.1

How to reproduce:

You can reproduce this with the bakery app by adding an icon which does not exist in the class CustomBootstrapListener

head.append(…)

[sandu-c]

seems has been fixed (somehow) in vaadin 1.14.2 but it is still reproducible when duplicating browser tabs, so if we duplicate browser tab

[knoobie]

I ran into this issue as well… took me quite some time to find the cause of it (missing UIScope on one component…) is there any way Vaadin could be a little bit more helpful in this scenario? The log message is not really intuitive.
