Node.js SDK 3.2.0 connecting with Couchbase enterprise Edition 6.6.2 build 9588 ‧ IPv4 , code crashes with segmentation fault


I have following code running on RHAT8 with node v14.16.0 . I am using latest Node SDK 3.2.0 which results in segmentation fault as shown below.

const couchbase = require(‘couchbase’);

//const DB_URL= ‘couchbase://localhost’;
const DB_URL = ‘’;
const DB_USER = ‘’;
const DB_PASSWORD = ‘’;
const DB_BUCKET = ‘folio-postings’ ;

const connOptions = {
username: DB_USER,
password: DB_PASSWORD
const cluster = new couchbase.Cluster(DB_URL, connOptions);
const bucket = cluster.bucket(DB_BUCKET);
cluster.diagnostics().then(res => {

        console.log("[Couchbase] - Connection successful");

}).catch(err => {

        console.log('[Couchbase] - Connection error => ', err);

const collection = bucket.defaultCollection();
collection.get(“folio_81231111”, (err, rows) => {
if (err) {
} else {

When I run above code I get segmentation fault:

[Couchbase] - Connection successful
Segmentation fault (core dumped)

If I run the same exact code and setting with Node.js SDK 3.1.1, it works fine. I see that Couchbase 6.5 is compatible with SDK 3.2.0 . Please advise what might be the issue.

Thank you for your help.
