Is the following use of next() allowed?
The update does not seem to work in this case, even when changes is a non-empty object. No error is raised, and when I printed the result, it has { value : null, done : true }. 
    
    const changes = { ... }
    let v0 = g.V(0);
    if (!(await v0.next()).value) {
        throw Error("Vertex not found.")
    }
    for (const [key, value] of Object.entries(changes)) {
        v0 = v0.property(key, value);
    }
    await v0.next();
    
    const changes = { ... }
    let v0 = g.V(0);
    if (!(await v0.next()).value) {
        throw Error("Vertex not found.")
    }
    for (const [key, value] of Object.entries(changes)) {
        v0 = v0.property(key, value);
    }
    await v0.next();

repeat and until methods in Javascript Gremlin:
I'm not particularly sure how to use them properly. From my current understanding, repeat() and until() are both instance methods of the GraphTraversal class, but how do I reference any methods within the class body but still refer to the same reference? 
const org = await g.V().until((r) => r.hasLabel('')).repeat({...}).path().by('name').next()
    
const org = await g.V().until((r) => r.hasLabel('')).repeat({...}).path().by('name').next()
What goes in the {...}? (If possible, can I see which imports you used if any in order to reference it completely? Much thanks.) For context, I'm trying to continue along in-edges until I reach a vertex labelled "b".
