NavigationPath(_items: SwiftUI.NavigationPath.(unknown context at

I tried to use navigationstack, and it works. but couldn't print the path, and with the message: " NavigationPath(_items: SwiftUI.NavigationPath.(unknown context at $7ff84b690a28).Representation.eager([SwiftUI.(unknown context at $7ff84b6907f0).CodableItemBox<Swift.String>]), subsequentItems: [], iterationIndex: 0). "

`import SwiftUI

var toDos: [String] = [ "list1", "list2", "list3" ]

struct ContentView: View { @State private var path = NavigationPath()

var body: some View {

NavigationStack(path: $path) {
    List {
        ForEach(toDos, id:\.self) { toDo in

            Button(action: {
                path.append(toDo)
                print(path)
            }, label: {
                Text("go to " + toDo)
            })
        }
    }
    .navigationDestination(for: String.self) { toDo in
        Text("page for " + toDo)
    }
}

} }

#Preview { ContentView() }`

I tried navigationlink and simulator still works fine, but cannot print anything of path
