deno deploy queues

is there a special flag or setting required for queues in deno deploy , i ceated a very simple example that works locally but not on deploy

app.get('/test', async(c) => {
  try {
    const env = await load();
    const db = await Deno.openKv();

    db.listenQueue(async(msg) => {
      const data = msg as { channel: string; text: string };
      console.log("=== QUEUE MESSAGE === ",data);
      await db.set(["test-queues", data.channel], data.text);
    });

    await db.enqueue({ channel: "C123456", text: "Slack message" }, {
      delay: 0,
    });
    return c.json({
      env,
    })
  } catch (error) {
    return c.text("error  with queues === "+error.message, 401);
  }
})

app.get('/test', async(c) => {
  try {
    const env = await load();
    const db = await Deno.openKv();

    db.listenQueue(async(msg) => {
      const data = msg as { channel: string; text: string };
      console.log("=== QUEUE MESSAGE === ",data);
      await db.set(["test-queues", data.channel], data.text);
    });

    await db.enqueue({ channel: "C123456", text: "Slack message" }, {
      delay: 0,
    });
    return c.json({
      env,
    })
  } catch (error) {
    return c.text("error  with queues === "+error.message, 401);
  }
})

The docs could do with updating but the db.listenQueue must be declared at the top level of your module on Deploy for it to work.

ohh, something like this ?

const db = await Deno.openKv();
db.listenQueue(async (msg) => {
  const data = msg as { channel: string; text: string };
  console.log("=== QUEUE MESSAGE === ", data);
  await db.set(["test-queues", data.channel], data.text);
  console.log("saved to kv ==== ",await db.get(["test-queues", data.channel]));
});

app.get('/test', async(c) => {
  try {
    const env = await load();
    // const db = await Deno.openKv();

    // db.listenQueue(async(msg) => {
    //   const data = msg as { channel: string; text: string };
    //   console.log("=== QUEUE MESSAGE === ",data);
    //   await db.set(["test-queues", data.channel], data.text);
    // });

    await db.enqueue({ channel: "C123456", text: "Slack message" }, {
      delay: 0,
    });
    return c.json({
      env,
    })
  } catch (error) {
    return c.text("error  with queues === "+error.message, 401);
  }
})

const db = await Deno.openKv();
db.listenQueue(async (msg) => {
  const data = msg as { channel: string; text: string };
  console.log("=== QUEUE MESSAGE === ", data);
  await db.set(["test-queues", data.channel], data.text);
  console.log("saved to kv ==== ",await db.get(["test-queues", data.channel]));
});

app.get('/test', async(c) => {
  try {
    const env = await load();
    // const db = await Deno.openKv();

    // db.listenQueue(async(msg) => {
    //   const data = msg as { channel: string; text: string };
    //   console.log("=== QUEUE MESSAGE === ",data);
    //   await db.set(["test-queues", data.channel], data.text);
    // });

    await db.enqueue({ channel: "C123456", text: "Slack message" }, {
      delay: 0,
    });
    return c.json({
      env,
    })
  } catch (error) {
    return c.text("error  with queues === "+error.message, 401);
  }
})
