I am using angular4 with loopback as api.

My application connects to my database fine. However, when I try to get data,

Answer 1

Ugh! This took way too much time to fix! For those of you who have the same issue. I had to do both:

1> I had this error, my problem was that I had not changed the database name from "test" to my own database when coping the connection string. – Meier Dec 8 '17 at 12:43

2>

"mongodb://:@cluster0-shard-00-00- rb899.mongodb.net:27017,cluster0-shard-00-01- rb899.mongodb.net:27017,cluster0-shard-00-02- rb899.mongodb.net:27017/?ssl=true&replicaSet=Cluster0-shard- 0&authSource=admin"

Also, In Atlas, you have to specify the older driver 2.2.12 or later. After doing these things it finally worked.

Thanks all!

Answer 2

In the Atlas cluster, select Security tab, press on button Edit then add a role readWriteAnyDatabase to the user. Try again or refresh your connection to see the result.

For anyone get the user is not allowed to do action [getLog] on [admin.] error. Had to explicitly give the user the clusterMonitor role

Answer 4

I had the same error myself.

• If you are using v.3.0 of the MongoDB NodeJS driver refer to MikaS post for the MongoClient.connect changes that need to be made. https://stackoverflow.com/a/47662979/8775223

• To connect your application to Atlas MongoDB use the 3.4 driver eg.

  mongodb://<USERNAME>:<PASSWORD>@cluster0-shard-00-00-
  rb899.mongodb.net:27017,cluster0-shard-00-01-
  rb899.mongodb.net:27017,cluster0-shard-00-02-
  rb899.mongodb.net:27017/<DBNAME>?ssl=true&replicaSet=Cluster0-shard-
  0&authSource=admin
  

Answer 5

Make sure to whitelist the IP you are using to connect from the Mongo CLI to your DB. Do this under the project Network Access tab.

Answer 6

If you are using v3.0 mongodb for Node.js you should use the new API as follows, and the MongoDB Atlas URI connection string for driver 3.4 and earlier:

MongoClient.connect(uri, function(err, client) {
  console.log("Connected successfully to server");

  const db = client.db(dbName);
});
