How can I fix this?

Hi! The error will be printed out regularly until the building_map_server runs, publishes the map and the map is received by the slotcar plugin.

Since parsing and publishing the map takes some time it is expected that it will be printed a few times until the map is received. Map publishing is part of the demos so it should really only be printed a few times then stop.
Does that happen or does it keep showing even after some time (let's say 30 seconds?)
