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

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;

Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.

This Unity version will no longer be receiving patch updates.

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()
