Problem opening multiple Buckets

I am running into a wired issue when trying to open more then one bucket at given time. In my app i have 2 main buckets, one is to store all email messages and notifications and then i have a bucket which stores the CRM info.
I have multiple sytems which open these buckets but always only one bucket per system. Now i have the need to open both buckets on one server at a time to validate a notification and then update the CRM of bounced message.

Here is how i went about it

var cluster = new couchbase.Cluster(config.cluster)
cluster.authenticate(config.userid, config.password)
let bucket = cluster.openBucket(config.bucket)
let bucket2 = cluster.openBucket(config.bucket_contact)
bucket.manager().createPrimaryIndex(function() {})
var N1qlQuery = couchbase.N1qlQuery;

and here is what i get when i try to make any call against the bucket 2

Error: cannot perform operations on a shutdown bucket

So question is how can I keep 2 Buckets open at the same time ?

Can you try perform the operations in the callback of the openBucket function, so that you guarantee the connection actually happened and the bucket variable is initialized. Something like:

cluster.openBucket(config.bucket, function(err) {
    if (err) console.log(err);
    else  {
         // create primary index
         // Or do querying
