Answer
The issue likely stems from the pageRank algorithm not detecting any meaningful connections between nodes, resulting in all scores being 0.0, which prevents any node from being marked as a landmark. Ensure your graph has edges connecting nodes (e.g., Problem → RootCause → Solution) to enable scoring. Verify the ETL pipeline correctly creates relationships and that the GDS procedure is invoked with the correct configuration. Example: `gds.pageRank.stream('graphName', { iterations: 10 })` should return non-zero scores if the graph is properly connected.
