[jira] [Commented] (TINKERPOP-2372) Encountered unregistered class
ID: 65536
[ https://issues.apache.org/jira/browse/TINKERPOP-2372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17113633#comment-17113633 ]
Stephen Mallette commented on TINKERPOP-2372:
---------------------------------------------
You should have a similar serializer configuration in Gremlin Server - is it possible that \{{JanusGraphIoRegistry}} isn't configured there?
