Spring Boot : Couchbase 5.0.1 - Could not connect to couchbaseDB

Question

I'm new to couchbaseDB and I encountering an issue connecting my spring boot application to database when I upgraded my couchbaseDB to 5.0.1.

Here is my configuration:

CouchbaseConfig.java

@Configuration
public class CouchbaseConfig {

   @Value("${spring.couchbase.bootstrap-hosts:localhost}")
   private String couchbaseUri;

   @Value("${spring.data.couchbase.bucket.name}")
   private String bucketName;

   public Cluster cluster() {
      return CouchbaseCluster.create(couchbaseUri).authenticate("user","password");
   }

   public Bucket bucket() {
      return cluster().openBucket(bucketName);
   }

I'm able to open the bucket I created but it will close immediately because of the exception and it always ask the "default" bucket's password which is not existing on the database. Here is the error log:

Error Log:

My question is how not to open"default" bucket and open only the bucket I created in the couchbaseDB? I hope you could help me regarding this matter. Thanks in advance.

This should not be happening unless I'm not seeing important parts of your code. Which couchbase sdk version are you using?

Here is a working example:

CouchbaseCluster server = CouchbaseCluster.create("testServer");
server.authenticate("user","password");
Bucket testBucket = server.openBucket("testBucket");

The above will only 'successfully' open testBucket if the user that authenticated (user) have access to it, else it will throw an InvalidPasswordException. You'll not be hitting any buckets in the above code but testBucket.
