Contributor guide
Research direction
Start by tracing QueryUtil.getType(StandardJanusGraphTx tx, String typeName) from VertexProgramScanJob through FulgoraGraphComputer, focusing on gremlin.traversalVertexProgram.haltedTraversers. Reproduce the exception with a non-AutomaticSchemaMaker setup and confirm that OLAP query execution handles the unknown type without failing.
