--------------------------------------
Hello Stephen,
Thanks for the quick reply. I am using AWS Neptune as the Graph DB.
Given i have a node with a label name=ben, age=43, and gender='male'
My application finds the node by id:
g.V().has('34bb4352-996b-3415-479c-86215a0796ff').valueMap().toList().then((val)=>
console.log(val));
this outputs the following to the console:
[ Map \{ 'gender' => [ 'male' ], 'name' => [ 'ben' ], 'age' => [ 43 ] } ]
However, when sending this to the response of my express res.send(val) -
produces [{}]
Similarly,
const map= *await* g.V().has(*'name'*,*'ben'*).valueMap().toList()
console.log( JSON.stringify(map))
results in the output of [{}]
Rather than a collection.
I am able to get an array of names if i populate a value within valueMap() But
gremlin touts that i shoudl get the collection running this method.
This also occurs not just with valueMap but with elementMap.
The following example from the gremlin-javascript npm fails for me as it
returns [{}] when serialized.
const findVertex = async (vertexId) => { const vertex = await
g.V(vertexId).elementMap().next(); return vertex.value; };
'
Please let me know what else i may be able to provide to understand how to help
or overcome this issue.

> Project: TinkerPop
> Issue Type: Bug
> Components: javascript
> Affects Versions: 3.4.9
> Reporter: Ben Smith
> Priority: Minor
>
> Sorry if I made this ticket incorrectly.
>
> I've installed gremlin as indicated.
> Running such a call as
> g.V(id).elementMap().toList(); fails to return from my client application
> output results is always [{}]
> same with return g.V(id).valueMap().toList();
> The above calls can output to the console correctly but not be serialized.
> Other toList calls work when the type is Vector. but seem to fail with Map.
> I am running Express, against Tinkertop 3.4.
