“InvalidOperationException: Not enough space in output buffer (need 24, has 0)” error is thrown when using NativeList.GetVertices()

-

Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Enter the Play Mode

Expected result: No error is thrown
Actual result: “InvalidOperationException: Not enough space in output buffer (need 24, has 0)” error is thrown

Reproducible with: 2020.3.48f1, 2021.3.26f1, 2022.3.1f1, 2023.1.0b19, 2023.2.0a17

Reproducible on: Intel MacOS 13.3.1

Note: The issue is not reproducible when using NativeArray.GetVertices()

  1. Resolution Note (2023.3.X):

    User code is wrong...

    Creating NativeList with initial capacity, but length of NativeList by default is 0. User needs to set Length before using it...

    newVertices = new NativeList<Vector3>(data.vertexCount, Allocator.Persistent);
    newVertices.Length = data.vertexCount;

  2. Resolution Note (2022.3.X):

    newVertices = new NativeList<Vector3>(data.vertexCount, Allocator.Persistent);
    newVertices.Length = data.vertexCount;
