Problem on a local data migration script

Working with Data

I would need help and explanation, I created a given migration script in local version but it works once on two wells with a concern that prevents the set from time to time.

const { MongoClient } = require("mongodb");

const url = "mongodb://127.0.0.1:27017";
const dbName = "";
const collectionName = "";

const client = new MongoClient(url);

async function main() {
  await client.connect();
  console.log("Connected successfully to server");

  const db = client.db(dbName);
  const collection = db.collection(collectionName);
  const result = await collection.find().toArray();

  result.map(async (d) => {
    await collection.updateOne(
      { _id: d._id },
      {
        $set: {
          ownerName: d.owners.primary,
          coowners: d.owners.additional,
          ownerID: "",
          discrim: "",
          status: "",
          serverCount: 0,
          shardCount: 0,
          analytics_visitors: 0,
          analytics_invites: 0,
          country: {},
          rates: {},
          dcwebhook: "",
          token: "",
        },
        $unset: {
          note: "",
          invite: "",
          state: "",
          donation: "",
          servers: "",
          auth: "",
          ratelimit: "",
          botLibrary: "",
          inRecomendationQueue: "",
        },
        $rename: {
          botid: "botID",
          avatar: "logo",
          description: "longDesc",
          long: "shortDesc",
          banner: "backURL",
          addedAt: "Date",
          certify: "certificate",
          likes: "votes",
        },
      }
    );
  });

  return "Action terminer";
}

main()
  .then(console.log)
  .catch(console.error)
  .finally(() => client.close());
