Managing duplicate queries using RequestQueue but it seems off.

import { RequestQueue } from "crawlee";

let jobQueue: RequestQueue;
async function initializeJobQueue() {
  if (!jobQueue) {
    jobQueue = await RequestQueue.open("job-deduplication-queue");
  }
}

async function fetchJobPages(page: Page, jobIds: string[], origin: string) {
  await initializeJobQueue();

  const filteredJobIds = [];
  if (saveOnlyUniqueItems) {
    for (const jobId of jobIds) {
      const jobUrl = `${origin}/viewjob?jk=${jobId}`;
      const request = await jobQueue.addRequest({ url: jobUrl });
      if (!request.wasAlreadyPresent) filteredJobIds.push(jobId);
    }
  } else {
    filteredJobIds.push(...jobIds);
  }

  myLog(
    `Filtered ${jobIds.length - filteredJobIds.length} duplicates, ` +
    `processing ${filteredJobIds.length} unique jobs.`
  );

  // fetchJobWithRetry and batching logic follows...
}
