---------------------------------------
Summary: gremlin subgraph step fail when vertices contains
properties with null values
Key: TINKERPOP-2109
URL: https://issues.apache.org/jira/browse/TINKERPOP-2109
Project: TinkerPop
Issue Type: Bug
Components: tinkergraph
Affects Versions: 3.3.4
Reporter: Bruno Supiot
We are currently using OrientDB as graph database backend. OrientDB allows
properties with null values. The orientdb database is requested with
Grooy/Gremlin request.
When we are requesting for a 'subgraph' step (which use the tinkergraph on
memory database for creating the subgraph), an exception is thrown when the
vertex of Orientdb contains properties with null values:
Part of the exception trace:
