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:
