I'm getting this error: MongoError: user is not allowed to do action [find] on [testdb.$cmd]

The issue is, I can connect to the database using mongo shell and it does everything I want just fine, but when I try it using node.js it always gives me that error when I connect to the database and try to do any actions. Here is the basic code I'm using to connect:

var uri = 'mongodb+srv://cluster0-woivk.mongodb.net/testdb'
MongoClient.connect(uri, {user: 'PaperDoom', password: 'TotallyNotReal'}, (err, db) => {
    if (err) console.log(err)
    //do stuff.
})
