Deserializer for "janusgraph:RelationIdentifier" not found

Hi All – I’m getting error “Deserializer for "janusgraph:RelationIdentifier" not found” when executing the below traversal using JanusGraph.Net:

 

await gtx.AddV("person").AddE("whatever").Promise(t => t.Iterate());

 

The stack trace:

I get this error any time I add any edge. Any help would be greatly appreciated!
