Hi all. I am getting an error when try to get properties of scene in Inspector.
I just choose scene and click on scene node, and getting this errors in console:
Also you can see inspector is empty.
send me the scene file and prefab files~
Here is my main.secene

I known, there is a: "__prefab": null,
But how to fix that problem. Also, how to prevent that issue.
Thanks in advanced!
Hi @sunstar,
I also have the same problem.
My steps:
- Create some 2d node (sprite).
- Create a folder called
prefabs. - drag a node to the prefabs folder to make it a prefab.
- try to add some components to the prefab (that display on the screen) like Box2d, rigid-body.
- Apply change to the original prefab.
- try to duplicate the current display prefab (instantiated).
It’s not always happened. But very easy to reproduce by repeat those steps.
I already tried cocos 3.2 & 3.2.1.
Error message in the console:
[preview-error]Uncaught TypeError: Cannot read property '__prefab' of null in http://localhost:7456/scripting/engine/bin/.cache/dev/preview/bundled/index.js
Could you please take a look?
can you send me the scene and prefab files (with .meta files)，so i can have a check~
Here is my project file: Filebin | k3q0u9w71xautqxm
I solved my problem.
Because the error looks weird.
My problem is about Feature Crop.
I disable physics 2d feature.
But then, I added BoxColider component.
So that component will be null.
Thank you so much for fast reply & help.
Sorry for this inconvenience.
