A sandbox file

sandbox.ts

async function sandbox() {
  await connect(process.env.MONGO_URI!);

  const alerts: {alertId: string; paymentId: string}[] = [];

  const paymentIds = alerts.map(alert => alert.paymentId);

  const payments: CardPaymentDoc[] = await PaymentModel.find({
    _id: {$in: paymentIds},
    cardInfo: {$exists: true},
  });

  const promises = payments.map(payment => {
    const alert = alerts.find(a => a.paymentId === payment._id.toString());
    if (!alert) return;

    payment.cardInfo.fraudReport = {
      requestId: alert.alertId,
      report: {},
    };

    return payment.save();
  });

  await Promise.all(promises);
}

const alert = alerts.find(a => a.paymentId === payment._id.toString());
const alert = alerts.find(a => a.paymentId === payment.paymentId.toString());

ah yes

Maybe also verify that the record wasn't already fraud alerted
