TigerGraph GraphRAG v1.4.2
GraphRAG 1.4.2 adds a knowledge graph compatibility check and repair tool, with reliability fixes for ingestion and sign-in.
What's New
- Knowledge graph compatibility check and repair — the Knowledge Graph Admin page can scan an existing graph for installed queries that have drifted from the shipped version or are missing, and repair them in place without rebuilding. Useful for picking up query fixes after a version upgrade on graphs that already hold data.
Changed
- Shipped query fixes apply automatically — on initialization, queries whose installed body has drifted from the shipped version are re-created, so improvements take effect after an upgrade without a manual reinstall.
- Clearer upload failures — when some files fail to upload, the document ingestion dialog names the affected files and the reason instead of failing the batch opaquely.
Bug Fixes
- Documents with spaces or mixed case in filenames now ingest reliably — they are stored under one consistent id across every ingest path instead of being silently skipped or duplicated, so they become retrievable and participate in entity extraction.
- Interrupted rebuilds recover cleanly — chunks left unfinished by a crashed or cancelled run are reconciled on the next run, eliminating chunks left without content and the spurious "missing content" warnings they caused.
- Sign-in respects configured TigerGraph ports — logging in works on deployments where TigerGraph runs on non-default GS/RESTPP ports.
