Issue Description

I added Deeplink support for json files to one of my Compose Screens like this

                composable(
                    route = Screens.screenB,
                    deepLinks = listOf(
                        navDeepLink {
                            uriPattern = "content://"
                            mimeType = "application/json"
                            action = Intent.ACTION_VIEW
                        }
                    ),
                    // with this not commented out, the app doesn't crash
//                    arguments = listOf(
//                        navArgument(name = "bla") {
//                            type = NavType.StringType
//                            nullable = true
//                            defaultValue = null
//                        }
//                    )
                ) {
                    val viewModel = hiltViewModel<ScreenBViewModel>()
                    ScreenB(
                        viewModel = viewModel,
                        onBack = navController::navigateUp,
                    )
                }

After opening a json file the app navigates to the correct screen, but when the user clicks on the toolbar back button and navigateUp is triggered the app crashes instantly with following stacktrace:

After adding a default argument to the nav composable the app doesn't crash, but it feels like a dirty workaround because the argument is never actively used.

Is it possible to read the file uri from an argument? if yes, how does the deeplink and the argument need to be declared?
