> The driver currently throws an exception that isn't very telling:
> {code:java}
> System.Collections.Generic.KeyNotFoundException : The given key
> 'janusgraph.RelationIdentifier' was not present in the dictionary. {code}
> It would be good if it would instead clearly state that no serializer was
> found for the GraphBinary type. This was first reported [on the
> janusgraph-users
> list|https://lists.lfaidata.foundation/g/janusgraph-users/message/6673].
> The exception gets thrown
> [here|https://github.com/apache/tinkerpop/blob/60b2792d63604b3baec68201adf35ed7f1d1e558/gremlin-dotnet/src/Gremlin.Net/Structure/IO/GraphBinary/TypeSerializerRegistry.cs#L282]
> for types received from the server where no serializer is registered for the
> driver.
> For the write path however, the exception thrown [is already more
> telling|https://github.com/apache/tinkerpop/blob/60b2792d63604b3baec68201adf35ed7f1d1e558/gremlin-dotnet/src/Gremlin.Net/Structure/IO/GraphBinary/TypeSerializerRegistry.cs#L224].
