nodejs and mongodb authentication failed

Question

I'm setting up a app with docker, mongodb and nodejs (mongoose), but for some reason I'm getting a authentication error.

UserNotFound: Could not find user "testuserdb" for db "admin"

Any suggestion?

Thanks!

.env

MONGO_USERNAME=testuserdb
MONGO_PASSWORD=testuserpass
MONGO_PORT=27017
MONGO_DB=testdb

db.js (mongoose connection)

const mongoose = require('mongoose');

const {
    MONGO_USERNAME,
    MONGO_PASSWORD,
    MONGO_HOSTNAME,
    MONGO_PORT,
    MONGO_DB
  } = process.env;

  const options = {
    useNewUrlParser: true,
    reconnectTries: Number.MAX_VALUE,
    reconnectInterval: 500,
    connectTimeoutMS: 10000,
  };

const url = `mongodb://${MONGO_USERNAME}:${MONGO_PASSWORD}@${MONGO_HOSTNAME}:${MONGO_PORT}/${MONGO_DB}?authSource=admin`;

mongoose.connect(url, options).then( function() {
    console.log('MongoDB is connected');
  })
    .catch( function(err) {
    console.log(err);
  });

docker compose I use a docker environment variables to mongodb and nodejs to define the username, password, hostname db, and databasename

version: '3'

As per the information available. I think the user testuserdb exist on testdb and not on admin database.

And while defining connection url you have mentioned authSource=admin

Change one of these as per your needs.
