Validation error upon run/build

Hey!

I've been working on my project for a little while now, and had to modify some entities within my group.
I remember using control-z to undo a color change on the color picker, and then saw another entity within my group disappear.

Ever since, i get a Null reference exception when i try to simply run, or build the project. Here is the error, and the stack

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. Unity.Tiny.TinyEntityGroup.Visit (Unity.Tiny.TinyProject+Visitor visitor) (at Library/PackageCache/com.unity.tiny@0.13.4-preview/Runtime/Runtime/Data/TinyEntityGroupVisitor.cs:16)

11. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

I'm looking for a way to correct this corrupted data, i've tried :
- Adding an entity with the same name/component
- Re-doing the whole entityGroup

Any help with this would be greatly apreciated!

 

So i don't see anything in the red within my entities, and i hold no references. I've got a total of 5 groups is my whole project. I'm looking through the .utdata to find the anomality right now.

 

So, turns out one of my entityGroup had an entity that i could not see from within the inspector.

To find which one it was, i've hack an output in the TinyEntityGroupVisitor script, using System.IO.
The last line written was the parent of my missing Entity.

The entity in question was a Panel, under a Canvas entity

For the curious, this is was i've used

Code (CSharp):

1. using System.IO;
2.  
3. namespace Unity.Tiny
4. {
5.     internal sealed partial class TinyEntityGroup
6.     {
7.         public void Visit(TinyProject.Visitor visitor)
8.         {
9.             using (System.IO.StreamWriter file =
10.             new System.IO.StreamWriter(@"./debug.txt"))
11.             {
12.                 visitor.VisitEntityGroup(this);
13.  
14.                 file.WriteLine("start");
15.                 foreach (var reference in Entities)
16.                 {
17.                     file.WriteLine("Ref + " + reference);
18.                     var entity = reference.Dereference(Registry);
19.                     visitor.VisitEntity(entity);
20.                     foreach (var component in entity.Components)
21.                     {
22.                         file.WriteLine("Comp " + component);
23.                         visitor.VisitComponent(component);
24.                     }
25.                 }
26.             }
27.         }
28.     }
29. }
30.  
31.  

 

So, I'm also stuck with this same issue and the only output I get from the debug.txt is this:

Code (CSharp):

1. start
2. Ref + Reference EnemySprite_Long
3. Comp Unity.Tiny.TinyObject
4. Comp Unity.Tiny.TinyObject
5. Comp Unity.Tiny.TinyObject
6. Comp Unity.Tiny.TinyObject
7. Comp Unity.Tiny.TinyObject
8. Comp Unity.Tiny.TinyObject
9. Comp Unity.Tiny.TinyObject
10. Comp Unity.Tiny.TinyObject
11. Comp Unity.Tiny.TinyObject
12. Comp Unity.Tiny.TinyObject
13. Comp Unity.Tiny.TinyObject
14. Ref + Reference Entity
15.  

Which I don't feel like is helpful at all?

It happened when I created an entity with a Text2DRenderer, Text2DStyle and NativeFont. Suddenly I can't build and play.
I've tried uninstalling/installing Utiny, deleted the Tiny folder + library and reimported everything but nothing seems to work :\

EDIT:
Okay so I was able to fix it, by reverting my changes in git.

 

Thank you @Michael-N3rkmind

My project was working fine yesterday and suddenly stopped today, after using your code, i have found out one of my EntityGroups became invalid.

God bless Git for let me revert everything back to a valid working state again .

Thank you again. Have a nice day!

 

I just want to add that I have had the validation errors a couple of times too. The way I solved them was just closing the tiny project and opening it again. Somehow this fixes it for me everytime. Might be that I got a different kind of validation error though..

 

Control Z is dangerous to use in Unity TIny from my experience. I usually save before i press it.

main issue iv noticed with it is it brings back all your deleted tiles alot of the times when you control Z anything. Same with duplicating
