Taylor Riggan updated TINKERPOP-2988:
-------------------------------------
Description:
The following throws an `Invalid OpProcessor requested [null] (499)` exception.
The cause is due to an invalid `RequestId` (an non-conformant UUID is being
used):
{{resp = client.stream ("g.V()", {}, \{ batchSize: 1, requestId: 'foo',
userAgent: 'bar', evaluationTimeout: 5000 });}}
The error was diagnosed using Gremlin Server 3.7.0 and seeing the following in
the server logs:
{{[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

represented by standard 36-char representation}}
