Redriver commented on TINKERPOP-2864:
-------------------------------------
This issue can be reproduced by adding the following testcase to
{code}
[https://github.com/apache/tinkerpop/blob/3.5-dev/gremlin-driver/src/test/java/org/apache/tinkerpop/gremlin/driver/ser/binary/GraphBinaryMessageSerializerV1Test.java]
{code:java}
@Test
public void shouldSerializeDefaultComputerResult() throws
SerializationException {
final ResponseMessage response = ResponseMessage.build(UUID.randomUUID())
.code(ResponseStatusCode.SUCCESS)
.statusMessage("Found")
.statusAttribute("k1", 1)
.result(new DefaultComputerResult(EmptyGraph.instance(),
EmptyMemory.instance()))
.create();
final ByteBuf buffer = serializer.serializeResponseAsBinary(response,
allocator);
final ResponseMessage deserialized = serializer.deserializeResponse(buffer);
assertResponseEquals(response, deserialized);
}
{code}
The error is like:
{code:java}

> Project: TinkerPop
> Issue Type: Bug
> Components: driver
> Affects Versions: 3.5.5
> Reporter: Redriver
> Priority: Major
>
> When I send the following request to gremlin-server, I got an error
> "{color:#1d1c1d}Serializer for type

> found{color}".
> {code:java}
> graph = GraphFactory.open('conf/fdb-psave-export.properties')
> graph.compute(SparkGraphComputer).program(CloneVertexProgram.build().create()).submit().get()
> {code}
> After investigation, I found GraphBinaryMessageSerializer cannot serialize
> DefaultComputerResult. The quick workaround is change the gremline to
> {code:java}
> graph = GraphFactory.open('conf/fdb-psave-export.properties')
> a=
> graph.compute(SparkGraphComputer).program(CloneVertexProgram.build().create()).submit().get()
> a.toString()
> {code}
> This asks the GraphBinaryMessageSerializer to serialize String instead of
> DefaultComputerGraph.
> I'm wondering is it possible to change the GraphBinaryMessageSerializer to
> automatically handle this.
