Pathfinding in a closed area

I just modified the original pathfinding demo. But i see that it's not working on closed areas. Is there a solution for it?

Your cell size is too big and gaps are too small.

Read about the cell size here:

Also maybe add events from pathfinding demo that provides a visual representation of the path by pressing key 'm' to your own project. It helps to see the path sometimes when testing.
