Re: Error during serialization: Cannot get namespace of root
David Pitera <piter...@...>
Hey Ramesh,
I have seen this issue before but only when the query you issue is actually returning a Graph reference itself; and I've only seen it in the context of an Http query. This leads me to believe there is an issue with the way the Http serializer serializes a graph reference.
It should be a no-stopper for you, as everything else should work as expected, and if you really don't like seeing that message, you can modify your gremlin scripts from something like `graph` to `graph; 0;` or `graph.vertices().size()` (anything that doesn't actually return a graph reference).
If you feel so inspired, please open an issue in the repo. I have a feeling but not sure that the fix might be at the TinkerPop level.
