MongoDB Auth Fails to find username on Bitnami MEAN Stack Image

Question

Trying to run a web app (MEAN) on Amazon EC2 Instance but am encountering the following problem. Can anyone help me with this?

node app.js The Server has started on 9091
/opt/bitnami/apps/YelpCamp/node_modules/mongodb-core/lib/auth/scram.js:128
    username = username.replace('=', "=3D").replace(',', '=2C');
                        ^

TypeError: Cannot read property 'replace' of undefined

Answer 1

Mongoose can do auth in 2 ways:

1, Connection string: mongoose.connect('mongodb://username:password@host:port(usually 27017)/db') Where username and password are the respective username and password for that specific db, host would be the host where your db is hosted (so localhost or some domain/IP), port is the port mongo listens on, and db is the name of the db you want to connect to

2, Using options. From the docs: var options = { useMongoClinet: true, auth: {authdb: 'admin'}, user: 'myUsername', pass: 'myPassword', } mongoose.connect(uri, options);

I also faced the 'username undefined' error in the first approach, but I succeeded in the second approach.
