## Summary - add an end-to-end Node regression matching LangChain PDFLoader metadata - verify create/query round trips rich nested `loc` and `pdf.info` fields against the currently configured Apache Arrow peer ## Root cause LanceDB v0.14 delegated nested object inference to Apache Arrow. Nested strings were dictionary-encoded with colliding dictionary IDs, so serializing query results as an IPC file failed with a dictionary-replacement error. Current `main` recursively infers nested fields and avoids those invalid dictionaries, but the reported LangChain path had no end-to-end regression coverage. ## Validation - `pnpm build` - `pnpm lint` - `pnpm run docs` - `pnpm test --runInBand` (678 passed, 5 skipped) Fixes #1963 <!-- lance-gatekeeper-fix:v1 agent=bf8d489db7db2e17678b143f9f0a36d2 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com> Co-authored-by: Xuanwo <github@xuanwo.io>

Usage
Basic Example
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
{ id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
