@spmallette Ok so your above code runs fine and returns a value. It appears
that my call to g.V(1).property() is not liked.
My request looks like this now:
`[RequestMessage{, requestId=7baf2b77-ca79-4679-9812-f3e0d8d3dbb5,
op='eval', processor='', args={gremlin=g.V(1).property(card, nm, val),
aliases={g=gmodern}, bindings={card={typeName=Cardinality, elementName=set},
nm=test, val=12}, language=gremlin-groovy,
accept=application/vnd.gremlin-v2.0+json}}]`
The full error I get is as follows:
`java.lang.IllegalArgumentException: The provided key/value array length
must be a multiple of two

What is the best way forward, your test proves that non native JS types are
being sent correctly, but my test should also work...
