I started the service using graphoper-web-5.3.jar and the configuration file as well as the OSM map.
After reading the OSM file, it displays: java.lang.runtimeexception: graph after reading OSM must not be empty.
I also noticed a line: c.g.reader.osm WaySegmentParser - pass1 - finished, processed ways: 1? 963, accepted ways: 0, way nodes: 0, relations: -1, totalMB:227, usedMB:94
Does it mean that osmreader filters out all the roads when reading the map?
My OSM map is converted from the SHP file using josm. There is only one Provincial Expressway Network structure, and the OSM file can be opened normally in josm
