Condition where-inV-is does not work

Hi, JanusGraph users. I try a simple query from TinkerPop docs with my JanusGraph installation, but it does not work as expected. How is it possible: gremlin> g.V(41099392).outE('LINK').inV() ==>v[110792] ==>v[81993864] gremlin> g.V(41099392).outE('LINK').where(inV().is(V(110792))) gremlin> The last query returns nothing... How to filter out vertices by traversal? Appreciate any help |

Thanks for reply. In real query I don't have an ID, that's why I use traversal in where clause. Tried this one, but it does not work either:
g.V(41099392).outE('LINK').where(inV().hasId(V(110792).id()))

Hi Anton, To compare objects you need the eq() predicate, not the is() step (see https://tinkerpop.apache.org/docs/current/reference/#a-note-on-predicates). Also note that JanusGraph uses RelationIdentifier objects as id's. So, give the following a try (not tested): g.V(110792).as('a').V(41099392).outE('LINK').where(inV().eq('a')) Best wishes, Marc Op woensdag 16 december 2020 om 10:03:33 UTC+1 schreef Anton Eroshenko:
