Error loading GraphSON data into a DSE graph with custom vertex ids

Question

I have created a schema with a custom vertex id like:

schema.vertexLabel('foo').partitionKey('_id').ifNotExists().create()

I then populated a graph with data. Now I'd like to transfer that data to another graph via GraphSON. The new graph instance has the same schema.

To do this I first exported the data from the populated graph:

graph.io(graphson()).writeGraph('/integration-data/flex-test-data.json')

However, when I try to import the data into the empty graph instance with:

graph.io(graphson()).readGraph('/integration-data/flex-test-data.json')

I get an error "Vertices with custom IDs must have their IDs specified on creation." This worked before I made the switch to custom ids. I have confirmed that the ids are present in the exported file.

Is this just not possible?

what version of DSE Graph are you running. There was a defect that was resolved in 5.1.6 for this issue.
