Null reference in Internal Script 101

[jeremya1a]

Hey guys,

We're trying to evaluate if Nova UI is a good solution for a small commercial VR simulation. Things are seemly working, but I am consistently seeing a null reference error coming line 87 of InteralScript_101.cs. We are using the free version 1.1.3 and Unity 2020.3.40f1.

There seems to be a null item in an collection of sorts.

Is there a fix to this? Are we missing something in a scene or such? Will this error cause issues or can it be ignored for the time being?

Hm... is that the only error you're seeing? It looks like one of Unity's APIs is a returning a list (a few lines up you can see we assign InternalVar_2 to UnityEditor.ActiveEditorTracker.sharedTracker.activeEditors) with a null element. As if a specific component's Editor has been destroyed, which is unexpected.

Thank you for bringing this to our attention. We'll be sure to investigate/publish a proper fix promptly.

In the meantime, a quick thing to try would be inserting this inside the loop, right before that faulty line:

if (InternalVar_2[InternalVar_5] == null)
{
    continue;
}

Does that at least unblock you? Or do more errors appear once that one goes away?

I think that'll fix it. Go ahead and mark this as resolved. Thanks for the quick response!

I'm not seeing any performance issues. Just hard to go to the boss and say this is the tool to use when it's throwing an unknown error. ;)

I've used Nova in personal projects and never seen this error. So it's possible it's particular to something in our project. I did bunch of testing before posting the issue and it was consistent. Even tried an uninstall and reinstall. Same result. I've now continued working just ignoring the error and I'm not seeing the error right now. So not sure so yeah maybe some internal Unity weirdness. I'll post more if I can figure out the cause, but thanks for the easy fix..
