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();
Solution:
It turns out, no, that's not allowed. It seems like done: true signifies that the traversal sequence was already committed and I'm doing basically nothing.

Commenting out the first next() allowed the second to work.
