NullReferenceException UnityEditor.SerializedObject..ctor

Question

Hello,

I keep getting the following error whenever I run my game:

NullReferenceException: (null) UnityEditor.SerializedObject..ctor (UnityEngine.Object[] objs) (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/SerializedPropertyBindings.cs:69) UnityEditor.Editor.GetSerializedObjectInternal () (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/EditorBindings.cs:117) UnityEditor.Editor.get_serializedObject () (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/EditorBindings.cs:110) UnityEditor.MeshRendererEditor.OnEnable () (at C:/BuildAgent/work/d3d49558e4d408f4/Editor/Mono/Inspector/MeshRendererEditor.cs:16)

I consistently get 6 of them. The problem is that when I click it, it doesn't take me to where in the script the error is so I have absolutely no clue how to debug this. I should mention that the game runs absolutely fine with the error, but I do not want this to cause any unexpected problem in the future.

How do I approach a problem like this?

Funny story... my Unity froze while I was trying to debug this, and when I restarted Unity the problem disappeared. So... I guess that's the answer.

Same here, was porting some models and animations from Blender to Unity and it popped around for no reason - restarting Unity fixed it. I guess its a engine issue?

Hate to necro this, but since it persists in 19.1.1f1: The problem is, you're previewing a Serialized object from your Project, in one (or both) of your Inspector windows. When you have 2 (or more) Inspector windows open while you preview a ScriptableObject Asset, you'll get that error and be unable to compile. The reason why "it fixed itself" by restarting Unity is that your Windows Layout did not save, so you restarted with only 1 Inspector window open.

TLDR: Close any other Inspector Windows you have open while previewing a Serialized object asset. Make sure you have only 1 Inspector Window open, while previewing your SerializedObject Asset.

I've submitted a Bug Report to hopefully have this fixed in the future.

I'm getting the exact same issue but when developing my own custom inspector for a specifc $$anonymous$$onoBehavior. It consistently happens in 2019.1 after I exit play mode. $$anonymous$$y custom inspector will also break when trying to access the serializedProperty member.

Can you link the Bug Report? I'd be interested in it

I still see the issue (Unity 5.6.0f3)... alt text

My configuration... alt text

Repro steps...

Create a configuration like in the second image (the material doesn't matter actually)
Run the game with the GameObject selected (it has to be selected before running the game)

Restarting the IDE makes it disappear but only until you select the GameObject again.

Note: The game works as expected. It's just an annoying error message.

Best regards.

Hey JaviTheGreat, I had the same problem. Restarting worked. I think the reason for the message is that there might be some variables which are initialized in the inspector and also in the start function of some script. Remove one of them, and it should help.
