After inserting a vertex in amazon neptune , I get the an unique id . If I want to print out the properties of a vertex , I can do it easily in gremlin console



enter image description here



But in my node js app , if I try to do the same I can't get the properties of the vertex



Here is what I have done in javascript



const fetchPropertyByVertexId = async (vertexId) => {
console.log("requsting properties of vertex "+vertexId);
return await g.V(vertexId).properties();
}


and then , I call



   fetchPropertyByVertexId(vertexId).then( property =>{
console.log(property);
});


And the output is



enter image description here



I am using this library to connect with amazon neptune .
How can I get property of a vertex , in key value pair , like I get it in gremlin console ?

          I think that you need to iterate your traversal. This:



          return await g.V(vertexId).properties();


          returns a Traversal object which does not return results - it just represents the object to iterate to get results. So, you need to include a terminal step like toList():



          return await g.V(vertexId).properties().toList();
