NullReferenceException on Undo.PerformUndo

Scripting

-

How to reproduce:
1. Open the attached Perform Undo NullRef.zip project
2. Go to Project window/Scenes/ open Sample Scene
3. Go to the Scene view and make sure Scene View tab is focused on by mouse
4. Press U button on the keyboard

Actual: NullReferenceException is thrown in the console window when performing Undo.PerformUndo

Reproducible with: 2019.3, 2020.2

Note: Could not test with earlier versions because of the thrown errors

  1. Resolution Note:

    It is safer to add a callback to beforeSceneGui instead of duringSceneGui when wanting to use undo actions.
    When using duringSceneGui the user can end up reversing some of the handle and tool set up unintentionally.
