CS1593(Delegate 'del' does not take 'number' arguments) but my constructor takes 3 arguments

Question

So im building a little game in unity and made a grid system with the help of a youtube tutorial so heres the code with the bug

public class GridBuildingSystem : MonoBehaviour
{
    private Grid<GridObject> grid;

    private void Awake()
    {
        int gridWidth = 38;
        int gridHeight = 38;
        float cellSize = 1f;
        grid = new Grid<GridObject>(gridWidth, gridHeight, cellSize, Vector3.zero, 
                                   (Grid<GridObject> g, int x, int y) => new GridObject(g, x, y));
}

public class GridObject
{
    private Grid<GridObject> grid;
    private int x;
    private int y;

    public GridObject(Grid<GridObject> grid, int x, int y)
    {
        this.grid = grid;
        this.x = x;
        this.y = y;
    }
}}

I get a CS1593(Delegate 'del' does not take 'number' arguments) on (Grid g, int x, int y) => new GridObject(g, x, y) but the constructor takes 3 arguments.

Edit: Maybe it has todo with this:

public class Grid<TGridObject> : MonoBehaviour
{
    private int width;
    private int height;
    private float cellSize;
    private Vector3 originPosition;
    private TGridObject[,] gridArray;
    private TextMesh[,] debugTextArray;

    public Grid(int width, int heigth, float cellSize, Vector3 originPosition, Func<TGridObject> createGridObject)
    {
        this.width = width;
        this.height = heigth;
        this.cellSize = cellSize;
        this.originPosition = originPosition;

        gridArray = new TGridObject[width, heigth];
        debugTextArray = new TextMesh[width, heigth];

        for(int x=0;x<gridArray.GetLength(0);x++)
        {
            for(int y=0;y<gridArray.GetLength(1);y++)
            {
                gridArray[x, y] = createGridObject();
            }
        }
    }
}

Hope anyone can help and have a nice day :D
