never mind....didn't read the question right
was (Author: spmallette):
What is the data type of "custom45"?
> Gremlin-Python: id object does not appear to be serializable

> Key: TINKERPOP-1881
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1881
> Project: TinkerPop
> Issue Type: Bug
> Components: python
> Affects Versions: 3.3.1
> Reporter: Taylor Riggan
> Priority: Blocker
>
> When attempting to add vertices and edges with custom IDs using the following
> traversal, Python returns an error stating that the returned object from the
> id built-in function is not serializable.
> Example traversal:
> {code:java}
> g.addV().property(id,"custom45").iterate()
> {code}
> Error / Stack trace:
> {code:java}
> Traceback (most recent call last):
