OrientDB Version:

Java Version:

OS: <Ubuntu 16.04.6 LTS>

Expected behavior

Gremlin-core: 3.4.4 On running this query
List<Map<String, Object> response = graph.traversal().V() .hasLabel("AwsEBSVolume") .as("AwsEBSVolume") .has("attr1", P.within("1")) .out("AwsEBSVolume"+ "_" + "Tag").as("a") .select("AwsEBSVolume", "a").toList() Expected behaviour is non null response.

Actual behavior

Steps to reproduce

Can not reproduce it. This error went away with a restart <An SQL script to reproduce the problem or a JUnit test case will increase A LOT the chance to have a quick fix>
