when I roslaunch hybrid_astar hybrid_astar.launch, the following error will occur:

Hi @hoppss @Hitoribc, can you guys try deleting the saved Voronoi graph once? Also, before passing a start/goal in Rviz, wait for the Voronoi graph to be calculated.

It solved when i deleted files below maps/cache/* . Thanks.

Yeah, seems like a bug in the Voronoi package. Might be able to solve it by including a deletion on startup in my code.
