Hello. I tried to import a osm file of this region right here: http://www.openstreetmap.org/export#map=15/53.9209/8.5007

but when i try to import the .osm via the graphhopper.sh i got this:

Can you please try

prepare.min_network_size=0
prepare.min_one_way_network_size=0

in the config.properties?

See this and this.
