What is causing this 'close resource' error with tests of KV in Deno 2?

I have some pretty simple Deno tests around retrieving some data from a Kv database. Using beforeAll I open a new DB and add some test data. Then using afterAll I close and delete the DB file.

When I run the tests, they all pass, but the describe level test fails because of this error.

getUserActions => https://jsr.io/@std/testing/1.0.4/_test_suite.ts:218:10
error: Leaks detected:
  - "database" was created during the test, but not cleaned up during the test. Close the resource before the end of the test.

I can verify that the the Kv data is actually deleted by just looking at the location where it shortly lived. What am I missing here to ensure the test framework understands that the db files have been deleted.

In other words, what is causing this error?

Here are some relevant file snippets.

// The Test
import { expect } from "jsr:@std/expect";
import { afterAll, beforeAll, describe, it, } from "jsr:@std/testing/bdd";

describe("getUserActions", () => {
  let kv: Deno.Kv;

  beforeAll(async () => {
    kv = await Deno.openKv("./test_data");
    await seedTestUserActionData();
  });

  afterAll(async () => {
    await kv.close();
    console.log("start delete");
    await deleteTestKv();
    console.log("end delete");
  });

// some tests follow
}

// database deletion functions
export async function deleteTestKv(
  dbPath: string = "./test_data"
): Promise<void> {
  await closeDb(dbPath);

  try {
    // Check if file exists before attempting deletion
    await Deno.stat(dbPath);
    await Deno.remove(dbPath);
    await Deno.remove(dbPath + "-shm");
    await Deno.remove(dbPath + "-wal");
  } catch (error) {
    if (error instanceof Deno.errors.NotFound) {
      console.log(`Database file ${dbPath} not found`);
    } else {
      console.log("Remove error:", error);
    }
  }
}

async function closeDb(dbPath: string): Promise<void> {
  try {
    // First try to close any existing connections
    const kv = await Deno.openKv(dbPath);
    await kv.close();
  } catch (error) {
    console.log("Close error:", error);
  }
}

It turned out that I wasn't closing the connection in the seedTestUserActionData function. That was the missing piece.
