Can't retrieve any documents from MongoDB using NodeJS/Express

Not sure why I am not getting any results from a GET call I am making with Postman.

Here is my server.js:

const express = require("express");
const mongoose = require("mongoose");
const app = express();

const uri =
  "mongodb+srv://[REDACTED]:[REDACTED]@cluster0.d5zbb.mongodb.net/?retryWrites=true&w=majority";

async function connect() {
  try {
    await mongoose.connect(uri);
    console.log("Connected to MongoDB");
  } catch (error) {
    console.error(error);
  }
}
mongoose.set("strictQuery", true);
connect();

const userRouter = require("./routes/users");
app.use("/users", userRouter);

app.listen(8000, () => {
  console.log("Server started on port 8000");
});

Here is my models/Users.js:

const mongoose = require("mongoose");

const userSchema = new mongoose.Schema({
  _id: mongoose.SchemaTypes.ObjectId,
  firstName: String,
  lastName: String,
  phoneNumber: String,
  isVendor: Boolean,
});

module.exports = mongoose.model("User", userSchema, "users");

And here is my users.js route:

const express = require("express");
const router = express.Router();
const User = require("../models/User");

router.get("/", async (req, res) => {
  try {
    const users = await User.find({});
    console.log(users);
    res.json(users);
  } catch (error) {
    res.sendStatus(500);
    console.log(error.message);
  }
});

module.exports = router;

In MongoDB, I have a users collection under a database and here is sample data:

{"_id":{"$oid":"63f90e2c00f411064f0415a8"},"firstName":"John","lastName":"Customer","phoneNumber":"1111111111","isVendor":false}

The endpoint I am hitting is http://localhost:8000/users but it always console logs an empty array. Literally any kind of help is truly appreciated. Thanks!
