Question I'm getting this error??

NullReferenceException: Object reference not set to an instance of an object
UnityEditor.GameObjectInspector.ClearPreviewCache () (at <67055f1be3654e2a987254d5437ee5b8>:0)
UnityEditor.GameObjectInspector.ReloadPreviewInstances () (at <67055f1be3654e2a987254d5437ee5b8>:0)
UnityEditor.GameObjectInspector.OnForceReloadInspector () (at <67055f1be3654e2a987254d5437ee5b8>:0)
UnityEditor.Tilemaps.GridPaintPaletteClipboard:OnDisable() (at D:/Unity 2019.4/2020.1.6f1/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.2d.tilemap/Editor/GridPaintPaletteClipboard.cs:347)

I think it has something to do with the 2D Tilemap Extras Preview I have used at some point?

Please help : /

 

The answer is always the same... ALWAYS!

Do not post for this error. Simply do these three steps:

How to fix a NullReferenceException error

https://forum.unity.com/threads/how-to-fix-a-nullreferenceexception-error.1230297/

Three steps to success:
- Identify what is null <-- any other action taken before this step is WASTED TIME
- Identify why it is null
- Fix that

 

No offence but this error has nothing to do with any code I have written.

It started to appear shortly after using the 2D Tilemap Extras Preview package?

I have tried to troubleshoot the error with Bard and ChatGPT... they both suggested to come to these forums??

I am very sorry if I have caused any reason for you to be angry with me. But please take another look at the error... it mentions the preview cache needs to be cleared?? And I have no idea what to do. If you are unable to help me. Could you please link me to someone who can?

Sincerely, flawmore

 

You're correct. Apologies. Try removing and reinstalling the package (looks like Tilemaps??). Try figuring out which tile or palette has the problem, see if it has anything wrong with its setting, missing tiles, etc.
