Hi all, Pretty new to neo4j and am playing around with it to store some ontology data. So far my experience has been pretty good but I am running into an odd issue when trying to get the shortest path between two nodes using the REST API. The command I am using is the following:
curl -H Accept:application/json -H Content-Type:application/json -X POST http://localhost:7474/db/data/node/7212/paths -d '{"to":"http://localhost:7474/db/data/node/2499","relationships": {"type": "is_a", "direction": "in"}, "algorithm": "shortestPath", "max depth": 50000}' Which fails and prints out the following exception: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <title>Error 500 Node[7025] not connected to this relationship[552]</title> <head> <body><h2>HTTP ERROR 500</h2> <p>Problem accessing /db/data/node/7212/paths.

Any help would be appreciated here, thanks! Cesar _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
