Bill Poole closed TINKERPOP-2787.
---------------------------------
Resolution: Workaround
Gremlin.Net works as expected when using a List<T> instead of an array T[].
> Cannot pass list of maps to withSideEffect in Gremlin.Net
> ---------------------------------------------------------
>
> Key: TINKERPOP-2787
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2787
> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet
> Affects Versions: 3.6.1
> Reporter: Bill Poole
> Priority: Major
>
> I’m trying to use the withSideEffect() configuration in Gremlin.Net to add a
> list of maps to GraphTraversalSource like is done in the [Long
> Traversals|https://tinkerpop.apache.org/docs/current/recipes/#long-traversals]
> recipe and the server throws an exception – “Could not deserialize the
> Traversal instance java.lang.IllegalStateException: Could not locate method:
> GraphTraversalSource.withSideEffect(String, LinkedHashMap, LinkedHashMap)”.
> The .NET code that reproduces the error:
> {code:java}
> var server = new GremlinServer("localhost", port: 8182);
> var client = new GremlinClient(server);
> using var connection = new DriverRemoteConnection(client);
> var g = AnonymousTraversalSource.Traversal().WithRemote(connection);
> var data = new[]
> {
> new Dictionary<object, object> { { "x", 1 }, { "y", 2 } },
> new Dictionary<object, object> { { "x", 3 }, { "y", 4 } }
> };
> await g.WithSideEffect("data", data).V().Promise(t => t.ToList());{code}
> However, I can pass an array of maps to the "inject" step just fine:
> {code:java}
> await g.Inject<object>(data).Promise(t => t.ToList()); {code}
> Passing an array of maps to “withSideEffect” as above produces the following
> error on the server:
> ERROR org.apache.tinkerpop.gremlin.server.op.traversal.TraversalOpProcessor
> - Could not deserialize the Traversal
> instancejava.lang.IllegalStateException: Could not locate method:
> GraphTraversalSource.withSideEffect(String, LinkedHashMap, LinkedHashMap)
