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 that connect nodes meaningfully (e.g., Problem → RootCause → Solution). Verify the edge direction and existence using `MATCH (n)-[r]->(m) RETURN COUNT(r)`. ```cypher MATCH (n)-[r]->(m) RETURN COUNT(r) ``` If no edges are found, the pageRank algorithm cannot compute scores. Check your ETL pipeline for edge creation logic.
