Idempotency - not working?

[ortschun]

Hey folks, I'm new to inngest and loving the product so far. Currently, I am having difficulties with getting the idempotency key to work. I might be missing something regarding the functionality.

The behavior I am expecting is, when there's a send event, if the id field is set, it will only run a single send call for a given particular id and drop the other send events.

I'm on nextjs, and have this function below using the same const idempotencyKey, testing on local development stack, with local inngest running, called literally one after the other.

await inngest.send({
    id: idempotencyKey,
    name: CREATE_GOOGLE_CALENDAR_INVITE_EVENT_NAME,
    data: data,
  });
  await inngest.send({
    id: idempotencyKey,
    name: CREATE_GOOGLE_CALENDAR_INVITE_EVENT_NAME,
    data: data,
  });
  await inngest.send({
    id: idempotencyKey,
    name: CREATE_GOOGLE_CALENDAR_INVITE_EVENT_NAME,
    data: data,
  });

I expect this to trigger only once but I see all 3 events succeeding, creating 3 calendar invites. Would love to understand if I'm not using idempotency in the intended way, or running into an inngest issue!
