"ServerError" on a request.

[AnthonyRyck]

Hello,
I have a problem, when I request the database (JanusGraph). I warn, I apologize in advance for my level of English.
This is the request. It repeats what was put in my last question.

var paths = await _g.V<SystemSolar>().Where(x => x.SolarSystemName == startSystm)
			.RepeatUntil(repeat => repeat.Out().SimplePath().Cast<SystemSolar>(),
						until => until.Where(x => x.SolarSystemName == arriveSystem))
			.Path().Limit(1);

I have a small change from the answer and it worked, I had itineraries.

var path = await _g.V<SystemSolar>().Where(x => x.SolarSystemName == startSystm)
		.RepeatUntil(repeat => repeat.Out().SimplePath(),
				until => until.Where(x => x.SolarSystemName == arriveSystem))
		.Path().Limit(1);

I had .Cast<SystemSolar>(), else the code do not compile.

So I had results coming out, I did a little refacto, and there I have this error that comes back all the time on this query.
The error :

To replay this error :

I use a docker container, janusgraph.

docker run --name janusgraph -d -p 8182:8182 janusgraph/janusgraph:latest

I have create a github repository with a little project.
https://github.com/AnthonyRyck/ShareProjectToTest.git

This is a test project to see how JanusGraph and the Gremlinq library work. I use data from the game EveOnline. I create a Graph that represents solar systems and the connections between systems. The goal is to calculate the route from one point to another.
The universe is divided into regions, and in one region there are several solar systems.
I put a site that calculates routes, and this represents the graph of a region: "The Forge". dotlan

To test, I'm trying to calculate the route Jita to Mitsolen with the method

loadData.GetItineraire("Jita", "Mitsolen").Wait();

Thanks for you help, I tried 1001 things, but here I can't find it, even though I know it worked!
