Sources: https://github.com/langchain-ai/langgraph/issues/8808. This is an external report; KFA has not reproduced it. Reported symptom: The issue author configured index={\"dims\": 2, \"embed\": <recording embeddings>, \"fields\": [\"text\"]} and stored an item with both a `text` field and a `metadata` field. The embedder received the full JSON of the item rather than only 'indexed', and the store_vectors table held field_name '$' rather than 'text'. The author expected only the `text` field to be embedded. Source: https://github.com/langchain-ai/langgraph/issues/8808.\n\nEnvironment: The reporter lists Linux, Python 3.14.7, langchain_core 1.5.2 and langsmith 0.8.18, and does not give the sqlite package version. A later commenter reports reproducing on langgraph-checkpoint-sqlite 3.1.1 with a stub embedder that records its input; with `fields`, the whole value was embedded and field_name was '$'. Other versions are unknown. Source: https://github.com/langchain-ai/langgraph/issues/8808#issuecomment-5885969094.\n\nReported cause (unconfirmed by maintainers): The same commenter says _ensure_index_config in the SQLite store reads `text_fields` rather than `fields`. They say `fields` is the key declared on IndexConfig and used in the package's own docstrings, and that InMemoryStore and PostgresStore already read `fields`. The issue author likewise says earlier PRs #4343 and #4345 fixed the same mismatch for PostgresStore. This is a code-reading claim by non-maintainers and has not been checked by KFA.\n\nImpact reported: Because the whole item is embedded, fields intentionally left out of the index may still be sent to an external embedding provider, and search results may be affected. Source: https://github.com/langchain-ai/langgraph/issues/8808.\n\nWorkaround (reported, not verified by KFA): Both the author and the commenter report that using the undocumented `text_fields` key yields the expected result, with embed input 'indexed' and field_name 'text'. Because the key is undocumented, it could change if a fix lands. Source: https://github.com/langchain-ai/langgraph/issues/8808.\n\nFix status: The issue is open. A commenter describes a proposed one-line patch that prefers `fields` and falls back to `text_fields`, and says it has regression tests and a passing suite. No PR, merge commit or release is linked in the supplied sources, so there is no confirmed fix and no shipped release. Closure is not applicable.
