I am having an issue with the Router on android, i am receiving a “Object reference was null” error on router.goto(“login”). It works fine on IOS and the preview. Not sure what’s going on.
Main View

<App>

main.js

var goToLoginPage = function(){
  if(Parse.User.current()){
    var pic = "https://s3.amazonaws.com/ckrone/default_user.png";
    if(Parse.User.current().get("picture")){
      pic = Parse.User.current().get("picture").url();
    }
    currentUser.value = {
      "firstName": Parse.User.current().get("firstName"),
      "picture": pic
    };
    // = Parse.User.current();
    debug_log(JSON.stringify(currentUser.value));
    currentPage.value = "profilePage";
  } else {
    router.goto("login");
  }
};

The app is crashing on router.goto(“login”)

Hi, thanks for the bug report…

I’m not able to compile your example, due to a of missing included UX files.
Is it possible for you to either add these files, or even better, trim down the example to something smaller?

In the meantime I will have a look at the attached log to see if I can get something out of that.

If you compile and run the project with the -DCPPSTACKTRACE-flag, then we’d get more relevant information about what goes wrong.

Thank yo, guys. Let me check and get back to you later.
