Help - Lookup array showing only Object without fields

I have query like this:
Stage 1:

{
  from: "scrapetrades",
  as: "scrape",
  localField: "_id",
  foreignField: "product",
}

Stage 2:

{
  from: "scrapetradeurls",
  localField: "scrape._id",
  foreignField: "scrape",
  as: "scrape.scrape_trade_urls",
}

Stage 3:

{
  from: "scrapetradeurllists",
  localField:
    "scrape.scrape_trade_urls.scrape_url_list",
  foreignField: "_id",
  as: "scrape.scrape_trade_urls.scrape_url_lists",
}

Stage 4:

{
  from: "scrapetradeurllogs",
  as: "scrape.scrape_trade_urls.scrape_url_logs",
  let: {
    scrape_url_id: "$scrape_url",
  },
  pipeline: [
    {
      $match: {
        $expr: {
          $eq: [
            "$scrape.scrape_trade_urls._id",
            "$$scrape_url_id",
          ],
        },
      },
    },
    {
      $limit: 1,
    },
  ],
}

Result from queries above showing scrape and scrape_trade_urls only Object without showing the document fields :

I want to convert result like this:
