how to use convertMeshTriPointsToClosedContour?

				vIDtemp = VertId(j);

	}

	auto result = convertMeshTriPointsToClosedContour(meshOrg, cutPoints, MR::SearchPathSettings({ MR::GeodesicPathApprox::DijkstraAStar, 100 }));

	if (result.has_value())
	{
		vector<OneMeshContour> contours;
		contours.push_back(move(result.value()));

		auto resultCut = cutMesh(meshOrg, contours).resultCut;

		auto mesh0 = fillContourLeft(meshOrg.topology, resultCut);
		auto mesh1 = meshOrg.topology.getValidFaces() - mesh0;

		Mesh resultMesh0 = Mesh();
		resultMesh0.addPartByMask(meshOrg, mesh0);
		Mesh resultMesh1 = Mesh();
		resultMesh1.addPartByMask(meshOrg, mesh1);

		VxConvertMRMeshToVx(resultMesh0, pCMeshOut0);
		VxConvertMRMeshToVx(resultMesh1, pCMeshOut1);

		return true;
	}

	return false;
}

After applying convertMeshTriPointsToClosedContour, result.value() returns false, but I don't know the reason. I've checked the parameters, but I'm not sure if I applied them incorrectly. So I'm asking for help.

The function convertMeshTriPointsToClosedContour returns Expected<OneMeshContour> type, which has 3 main methods has_value(), value(), error():

• has_value() returns true on function's success and false otherwise,
• value() can be called only if has_value()==true,
• if has_value()==false, please call error() method, which will return you a string with the description of what went wrong.
