This fails on query but works on describe. Why?

vectorize_problem.ts

import { getPlatformProxy } from "wrangler";

(async () => {
  const proxy = await getPlatformProxy<Env>();

  /// This succeeds!
  const vectorizeIndex = await proxy.env.VECTORIZE_INDEX.describe();
  console.log(vectorizeIndex);

  const vector = new Array(1024).fill(0);

  /// This fails!
  const result = await proxy.env.VECTORIZE_INDEX.query(vector, {
    topK: 1,
    returnMetadata: "all",
    namespace: "test",
  });

  console.log(result);
})();
