Trying to find a Vertex using a variable injected earlier in the traversal

I am trying to add a series of vertices and edges to an existing graph. The newly created Vertex will be the

to

Vertex. From business logic, I will know the ID of the

from

from

Vertex for the new Edge . I am able to create the new Vertex without any issue, but when I am having trouble grabbing the

from

from

Vertex to create the edge. Is there a way to do this/what am I doing wrong?

g.inject(["myID": "2", "parentID": "1", "properties": ["key1":"value1"]]).
addV("MyVertex").as("newVertex").
property(id, select("myID")).
sideEffect(
    select("properties").unfold().as("kv")
    select("newVertex").
    property(
        select("kv").by(keys),
        select("kv").by(values),
    )
).
AddE("MyEdge").to("newVertex").from(V(select("parentID")))

g.inject(["myID": "2", "parentID": "1", "properties": ["key1":"value1"]]).
addV("MyVertex").as("newVertex").
