Error triangulating mesh. Aborted with more than 4 polygon points

I tried your code but it failed with an L shape like this

        points.Add(new Vector2(1, 0.25f));
        points.Add(new Vector2(1, 0));
        points.Add(new Vector2(0, 0));
        points.Add(new Vector2(0, 1));
        points.Add(new Vector2(0.25f, 1));
        points.Add(new Vector2(0.25f, 0.25f));
        points.Add(new Vector2(1, 0.25f));
