My web server connected to mongoDB is not responding

Question

I'm new to node.js

https://devforum.roblox.com/t/saving-player-data-to-mongodb-atlas-in-the-cloud-scaleable-well-maintained/632977

I am making a web server connected mongoDB after watching this tutorial.

I am testing my web server using postman, response.send indicating success or not is output normally, but my mongoDB is unchanged

How it works is https:///player-data/ as in the tutorial

What do I need to fix?

// We create a POST route
app.post("/player-data/update-coins/:id", async (request, response) => {
  // We use a mongoose method to find A record and update!
  await playerModel.findOneAndUpdate(
    { userID: `${request.params.id}` },
    { $set: { coins: request.body.coins } }
    // We set the coins to the coins we received in the body of the request
  );
  response.send("Updated Database.");
  // Just a response.
});
