我正在开发一个使用 jetpack compose 的 Android 聊天应用程序，该应用程序有一个 NavHost，在某些可组合项中带有一些深层链接，当从浏览器或聊天应用程序打开链接时，应该打开深层链接后面的屏幕，但它不起作用，并且出现以下错误：
Fatal Exception: java.util.NoSuchElementException: Sequence is empty.

这是我的导航主机：
NavHost(
navController = navController,
startDestination = initialRoute
) {
composable(
route = AppScreens.ChatScreen.route + "/{${NavArgumentKeys.chatId}}" + "?${NavArgumentKeys.newChat}={${NavArgumentKeys.newChat}}",
arguments = listOf(
navArgument(NavArgumentKeys.chatId) { type = NavType.IntType },
navArgument(NavArgumentKeys.newChat) { type = NavType.BoolType; defaultValue = false }
),
deepLinks = listOf(
navDeepLink {
uriPattern = "https://example.com/{${NavArgumentKeys.chatId}}"
action = Intent.ACTION_VIEW
}
),
) {
val chatId = it.arguments?.getInt(NavArgumentKeys.chatId)
val newChat = it.arguments?.getBoolean(NavArgumentKeys.newChat)
val chatViewModel = hiltViewModel<ChatViewModel, ChatViewModel.ChatViewModelFactory>(key = chatId.toString()) {
factory -> factory.create(chatId!!, newChat!!)
}
ChatScreen(
viewModel = chatViewModel,
preferences = preferences,
)
}
}
这是 Android 清单：

我尝试通过以下方式从 Google Keep 打开此链接“https://example.com/0”：
如果通过单击或按下从 Google Keep 打开链接时可以正常工作，则应用程序应打开并显示 URL 后面的号码所属的 ID 的聊天。
如果您导航至
