Description

Looking at the implementation I think we don't actually need this check. The current implementation indexes the sparse vectors used and returned by the method are index by the position of the vertexId in `sources` not by the vertex ID itself. We should remove this check and add a test to confirm the implementation works with large vertex IDs.
