MongoDB oplog stream Node.js

I have a local instance of MongoDB, started with --master, and I can see in the start log that I have a replica set oplog (file: /data/db/local.1) created. And it appears local.1 is updated every time I perform and insert().

I am trying to tail / stream the oplog with the following code...

MongoDB.connect('mongodb://localhost:27017/test',(e,db) => {
          if ( e ) { return console.log('Connect MongoDB Error',e); }
          console.log('Connected MongoDB'); 
          Server.DB = db;  
              db.collection('oplog.rs').find({}).toArray((e,d) => {
                console.log('oplog.rs');
                console.log(e);
                console.log(d);
              })  

          var updates = db.collection('oplog.rs').find({},{ 
                              tailable: true, 
                              awaitData: true, 
                              noCursorTimeout: true, 
                              oplogReplay: true, 
                              numberOfRetries: Number.MAX_VALUE 
                              }).stream();
                              
              updates.on('data',(data) => { console.log('data',data); });
              updates.on('error',(e) =>   { console.log('error',e); });
              updates.on('end',(end) =>   { console.log('end',end); });
        });

The Code logs the following on start...

oplog.rs
null
[]

However there is no output from stream, I set numberOfRetries to a lower value I get the error..
