Describe the bug

When I try to run batches using taskName.batchTriggerAndWait or batch.triggerByTaskAndWait they are able to run correctly until I provide the idempotencyKey option to the runs. Then the batch never completes.

To reproduce

Here is a simple example I used to reproduce:

import { task } from '@trigger.dev/sdk';
import { idempotencyKeys, wait } from '@trigger.dev/sdk';

const getOne = task({
  id: 'get-1',
  run: async () => {
    await wait.for({ seconds: 10 });

    return 1;
  }
});

export const sumBatch = task({
  id: 'sum-batch',
  run: async (): Promise<number> => {
    const result = await getOne.batchTriggerAndWait([{
      payload: null,
      options: {
        idempotencyKey: await idempotencyKeys.create('get-1', { scope: 'global' }),
      },
    }, {
      payload: null,
      options: {
        idempotencyKey: await idempotencyKeys.create('get-1', { scope: 'global' }),
      },
    }, {
      payload: null,
      options: {
        idempotencyKey: await idempotencyKeys.create('get-2', { scope: 'global' }),
      },
    }, {
      payload: null,
      options: {
        idempotencyKey: await idempotencyKeys.create('get-3', { scope: 'global' }),
      },
    }]);

    return result.runs.reduce((acc, curr) => {
      if (curr.ok) {
        return acc + curr.output;
      }
      return acc;
    }, 0);
  },
});
