Deserializing of Vertex ID with Custom String value
Hi,
I've come across an issue with deserialization from users enabling custom vertex ID values and types as documented on https://docs.janusgraph.org/advanced-topics/custom-vertex-id/.
Below is a sample GraphSON serialization error highlighting the issue, where a vertex has a custom string ID value (U933779):
The part that confuses me is the RelationIdentifier class as defined in JG 1.0 (https://github.com/JanusGraph/janusgraph/blob/12708188397f69616adddc933e539e841af409e4/janusgraph-driver/src/main/java/org/janusgraph/graphdb/relations/RelationIdentifier.java#L31) still defines the id value as a long.
My question is, for custom vertex id values, what is the correct approach to deserializing ID values? We've tried this with multiple different types of serializers to no avail.

Solution
Hey, turns out it was a mismatch between driver and server version due to the user being on an older version of G.V(), i need to remember to make this the first thing i check
