#1606 dealt with it here

[MarceloRGonc]

Extract to a method:

function splitSubscriptionListIntoBatches(
  subscriptionList?: string[],
): (string[] | undefined)[] {
  if (!subscriptionList?.length) {
    return [undefined];
  }

  const batches: string[][] = [];
  for (let i = 0; i < subscriptionList.length; i += BATCH_SIZE) {
    const batch = subscriptionList.slice(i, i + BATCH_SIZE);
    batches.push(batch);
  }

  return batches;
}

    const allResults = await getQueryResults(
      splitSubscriptionListIntoBatches(subscriptionList),
      buildResourceGraphUrl(apiVersion),
      headers,
      kql,
      normalizedMax,
    );
