Error when baking the Navmesh

[GaLzZy]

Hi i'm getting this NullRef error whenever I bake my Navmesh using modifiers on my tilemaps and NavigationCollectSources2d...

Thanks!

Looks like an issue, I'll take a look.

I played with some settings yesterday and in the end I got it to work so I couldn't tell you where it was coming from :/

I have a fairly similiar issue on which occours on multiple 2021.3 versions. The following exception at editor time as soon as i add a Navigation Surface component to a Scene:
NullReferenceException: Object reference not set to an instance of an object
NavMeshPlus.Components.Editors.NavMeshSurfaceEditor.RenderBoxGizmoSelected (NavMeshPlus.Components.NavMeshSurface navSurface, UnityEditor.GizmoType gizmoType) (at Library/PackageCache/com.h8man.2d.navmeshplus@ef1e438e70/NavMeshComponents/Editor/NavMeshSurfaceEditor.cs:310)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

For me I have this setup:

And whenever I put a Navigation Modifier on my Walls layer so the blue doesn't overlap on the walls, it errors out

Same issue here. It occurs on my 2021.3.34 version, I tried to create a new project based on 2023 version and it works properly.
Also works fine with 2022 version.

I am on Unity 6 which essentially is 2023

Debugging a bit and it seems the error arrises in the following block
https://github.com/h8man/NavMeshPlus/blob/6d8836e05af9cb9b5274e97d522ff0548423cf9e/NavMeshComponents/Scripts/NavMeshSurface.cs#L443C21-L448C22
Because the m.bounds variable is undefined, a patch work fix might be to make it like so but this would not fix whatever the root cause is

                    case NavMeshBuildSourceShape.Mesh:
                    {
                        var m = src.sourceObject as Mesh;
                        if (m != null)
                            result.Encapsulate(GetWorldBounds(worldToLocal * src.transform, m.bounds));
                        break;
                    }
