Working with cbc tool, I see that below error when creating a bucket which not relevant at all:
/opt/couchbase] $ ./cbc bucket-create test -u Administrator -P password
Requesting /pools/default/buckets
libcouchbase error: The bucket requested does not exist (0x19)
And also I see same that when trying the retrieve the documents as well.
Using couchbase-sever-community 4.0.1 version
libcouchbase version is 2.6.0
