Janusgraph with spring-data-gremlin - tinkerpop

Question

I am using the JanusGraph 0.5.3 with Cassandra as backend. With spring-data-gremlin version 2.3.0 along with spring-boot:2.5.0, tinkerpop:3.4.6, I am trying to connect to Janusgraph. A vertex could be successfully created and using gremlin console, I could query and view the vertex. But with spring-data-gremlin and tinkerpop, the de-serialization step is failing. Following the other posts and discussion, I used different ones including GraphSONMessageSerializerV3d0. The error message is

and the json, it is trying to serialize it is

Using gremlin console, I serialized the vertex and the json of the vertex is
{
"id": {
"#type": "g:Int64",
"#value": 1000
},
"label": "Product",
"outE": {
"also_bought": [
{
"id": {
"#type": "janusgraph:RelationIdentifier",
"#value": {
"relationId": "215st9-rs-8sut-8hk"
}
},
"inV": {
"#type": "g:Int64",
"#value": 11000
}
},
{
"id": {
"#type": "janusgraph:RelationIdentifier",
"#value": {
"relationId": "215t7h-rs-8sut-99c"
}
},
"inV": {
"#type": "g:Int64",
"#value": 12000
}
}
]
},
"properties": {
"name": [
{
"id": {
"#type": "janusgraph:RelationIdentifier",
"#value": {
"relationId": "215s0t-rs-35x"
}
},
"value": "Product-11"
}
],
"_classname": [
{
"id": {
"#type": "janusgraph:RelationIdentifier",
"#value": {
"relationId": "215sf1-rs-3yd"
}
},
"value": "com.divvet.store.productgraph.domain.Product"
}
]
}
}
This does not match up with the spring-data-gremlin serialization which has vertex nested two level down

The properties in remote-graph.properties is
gremlin.remote.remoteConnectionClass=org.apache.tinkerpop.gremlin.driver.remote.DriverRemoteConnection
gremlin.remote.driver.clusterFile=conf/remote-objects.yaml
gremlin.remote.driver.sourceName=g
and remote-objects.yaml is
hosts: [localhost]
port: 8182
serializer: {
className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV3d0,
config: { ioRegistries: [org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry] }}
For the serializer, I tried with all the serializers that are listed here
Please let me know if you need more details and how to resolve this.
