Sorry for the delay. I got a working example here:
I poked into it a little bit and it seems to be connected to
Steps to reproduce:
- Navigate from Second Fragment to Child nav graph (with non-nullable parameters).
- Navigate to Third fragment using SafeArgs and the app crashes.

Ups a typo: Navigate from Second First Fragment to Child nav graph (with non-nullable parameters).

Fix missing non-nullable arg when rebuilding hierarchy
When navigating with NavDirections, args is populated with an empty bundle. This causes issue when we rebuild parent hierarchy while adding a new entry to NavBackStack. If the Entry being rebuilt contains a non-nullalbe arg, i.e. Long, this empty bundle will cause an exception.
Test: ./gradlew navigation:navigation-runtime:cC

Guys, 2.3.0 doesn't have this fix included

Re #10 - it definitely does. Please file a new issue with a sample project that reproduces any issue you're having with Navigation 2.3.0.
Description
Component used: Navigation
Version used: 2.2.2
Devices/Android versions reproduced on: Emulator Android R, OnePlus 7 with Android 10
The issue appeared in 2.2.2, 2.2.1 works just fine. Error log:
This log appears TWICE, so both graphs failed while lookup. In version 2.2.1 this log appeared once, as expected, for the nested graph.
The issue here is that in
main_navigation
i have other navigation graph for intro flow (splash screen, onboarding etc). If in main_navigation i have only fragments - everything works fineScenario to reproduce problem on attached project
Pending intent in notification should point to main page, but it can't. Why? Because method
findInvalidDestinationDisplayNameInDeepLink
is looking for deep link handler twice. Once in propermain_navigation
. But the second time - it is looking for it inintro_navigation
, which doesn't have destination we are looking for. The changed line that broke things isgraph.findNode(destinationId, false);
. And it seems reasonable to me -intro_navigation
can't find proper node, but it's parent can. I can confirm that evaluatinggraph.findNode(destinationId, true);
returns proper node which is expected behavior.Please ask if i can provide you with more information. Full reproduction sample provided.
