Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. In Hierarchy, select the “Directional Light” GameObject
4. Observe the Console window
Expected result: No errors are present
Actual result: Error “NullReferenceException: Object reference not set to an instance of an object“ is spammed
Reproducible with: 7.0.0-exp.3 (2022.2.16f1), 7.0.0 (2021.3.35f1, 2022.3.20f1, 2023.2.12f1, 2023.3.0b9)
Not reproducible with: 6.4.2-preview.2 (2022.2.16f1)
Reproducible on: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested
Workaround:
In MLSpatialMapper.cs (Packages/com.unity.xr.magicleap/Runtime/Meshing/MLSpatialMapper.cs), change line:
{{m_MeshType = this.serializedObject.FindProperty("m_MeshType"); }}
to:
{{m_MeshType = this.serializedObject.FindProperty("m_RequestedMeshType");}}

Resolution Note:
The `FormerlySerializedAs` attribute is only meant to be used for serialized objects on disk, not for serialized objects in memory which is what the FindProperty() function works on.
The recommended solution is to update the string used in the FindProperty() function.
