Hi, We recently upgraded the Couchbase to 4.1.0 but when I tried to load the data from OLTP database to buckets thru Talend ETL job (windows batch file) it is failing with following error. I tried to fail-over/re-balance/remove nodes and add back with re-balance but nothing worked. We have two nodes in cluster. It was working fine with previous versions 3.1.0/2.1.1/2.1.0. Please check this and help.
