> Serialization error throws an Invalid OpProcessor exception when using
> stream() API
> -----------------------------------------------------------------------------------
>
> Key: TINKERPOP-2988
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2988
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.7.0
> Reporter: Taylor Riggan
> Priority: Critical
>
> The following throws an
> {code:java}
> Invalid OpProcessor requested [null] (499){code}
> exception. The cause is due to an invalid RequestId (an non-conformant UUID
> is being used):
> {code:java}
> resp = client.stream ("g.V()", {}, { batchSize: 1, requestId: 'foo',
> userAgent: 'bar', evaluationTimeout: 5000 });{code}
>
> The error was diagnosed using Gremlin Server 3.7.0 and seeing the following
> in the server logs:
>
> {code:java}
> [WARN] o.a.t.g.s.h.WsGremlinBinaryRequestDecoder - Serialization error while
> decoding request
> org.apache.tinkerpop.gremlin.driver.ser.SerializationException:
> org.apache.tinkerpop.shaded.jackson.databind.JsonMappingException: Could not
> deserialize the JSON value as required. Nested exception:
> org.apache.tinkerpop.shaded.jackson.databind.exc.InvalidFormatException:
> Cannot deserialize value of type `java.util.UUID` from String "foo": UUID has
> to be represented by standard 36-char representation

> A better client side error message is needed in order to provide the user
> with guidance on how to fix the issue. `Invalid OpProcessor` is too
> ambiguous.
