Fail to connect mongoose to Atlas-MogoDB

I have whitelisted my IP, and I have correctly replaced my username and password (including the special characters in the password) in the URI string, but it doesn't work. I also tried to allow access from everywhere, but the result was the same. I'm getting this error:

Server running on port 5000

  },
  [Symbol(mongoErrorContextSymbol)]: {}
}

This is my code:

require("dotenv").config();
const express = require('express');
const mongoose = require('mongoose');

const port =  5000;
const ATLAS_URI = process.env.ATLAS_URI;
const app = express();

app.use(express.json());

mongoose.connect(ATLAS_URI, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useUnifiedTopology: true
   })
  .then(() => console.log('mongoDB connected'))
  .catch(err => console.log(err));

  app.listen(port, () => console.log(`Server running on port ${port}`));

I've read posts, I've watched videos and spent several hours but I can't resolve this issue. Any ideas?

It turns out my password was causing the issue. I chose one with some special characters, and even though I followed the instructions in the documentation on how to encode them, somehow it didn't work. I terminated the cluster, created one with a password that didn't contain special characters and it worked.

Check that your connection credentials string isn't badly formatted so it contains HTML codes instead of just text i.e. %24.

Here is an example I used a while back. Also I had an error where it can't find the test db so change that in the URI too.

mongodb+srv://USERNAME:[email protected]/DATABASE_NAME?retryWrites=true&w=majority
